A strong foundation

Professor Daichao Sheng's research expertise covers the areas of unsaturated soil mechanics, computational geomechanics, cold region geotechnics and geo-environmental engineering.

Professor Daichao ShengProfessor Sheng, Head of Discipline of Civil, Surveying and Environmental Engineering, has a Bachelor of Science from Lanzhou University in China and a Licentiate in Engineering and a PhD from Lulea University of Technology, Sweden.

In his role as Co-Director of the Priority Research Centre for Geotechnical and Materials Modelling, Sheng will be chief investigator for a large 2015 ARC-funded study on the mechanics of hard soils and soft rocks, and will also be an investigator on another 2015 ARC-funded study on unsaturated soil-structure interaction with emphasis on buried pipelines.  

Hard soils and soft rocks are transitional materials that have properties evolving from soft rock to soft soil. They are widespread in Australia and typical examples include mudstone, claystones, shales and tuffs. These materials are very difficult to handle in construction, mainly due to the fact that their strength, stiffness and volume can change substantially in response to environmental actions such as wetting and drying. Proper prediction of the transitional behaviour of these materials is crucially important for analysing the stability and serviceability of civil structures founded on them.

The ARC-funded project aims to develop a theoretical and practical framework for characterising the transitional behaviour of hard soils and soft rocks. It will deliver a high-quality experimental data base and a validated theoretical framework that can encapsulate the behaviour of transitional geomaterials under environmental actions, and hence provide guidelines for handling these materials in civil works and tools for predicting the short- and long-term stability and serviceability of civil structures.

Professor Sheng has a prolific body of research to his name with over 110 journal articles and 82 conference papers to date. Career highlights include three international best paper awards and the Young Investigator Award at the 6th World Congress on Computational Mechanics which recognises the outstanding achievements of an investigator aged under 41 through their published works in computational mechanics.

Recently Sheng was awarded the John Booker Medal for his outstanding contribution towards understanding the behaviour of unsaturated soils and frozen soils, an award Sheng received in 2014 from the International Association for Computer Methods and Advances in Geomechanics. He is a Fellow of the Institute of Engineers Australia and also a Distinguished Professor at Central South University School of Civil Engineering in China, a role he has had since 2013. In the latter role, he is helping Chinese researchers and railway engineers to understand the unexpected frost heave in a high-speed railway embankment in north-east China. The unexpected frost heave has caused a significant reduction in train speed, from the design speed of 350 km/hour to an operational speed of 200 km/hour in winter seasons. Sheng's research also leads to practical solutions to the problem for future high-speed railway construction in cold regions.

In early 2014, Professor Sheng took on the role of Editor of the Canadian Geotechnical Journal, for which he served as an Associate Editor since 2008. First published in 1963, this is one of the three oldest geotechnical journals and was ranked as an A* journal in the ERA 2010 journal rankings. He is the first non-Canadian editor of the journal. In addition, he serves on the editorial boards of three other international journals.

With co-author Dr Jubert Pineda, in 2013 Professor Sheng was commissioned by the Office of the NSW Chief Scientist and Engineer to evaluate potential subsidence and possible mitigation measures that are available to minimise and control subsidence during coal seam gas extraction.

In 2014 Sheng received the Vice Chancellor's Award for Supervision Excellence in his Faculty, which recognises the important role supervisors play in supporting the University's PhD and research masters students. He is currently supervising five civil engineering PhD students.

"Working with PhD students is a satisfying and rewarding experience. We are not only solving challenging scientific and engineering problems, we are also training the next generation of research leaders. It satisfies me most to see my students and research associates doing well in their career," explains Sheng.

Sheng sums up his motivation for being involved in so many different arenas. "As an academic, we spend much our time, including weekends and holidays, reviewing and assessing our colleagues' work, in addition to our own research. It is difficult to understand our motivation from a financial point of view, but the bottom line is we are doing things that interest us. For me, research is the one thing that I'm most interested in and that I feel like I am doing best. I thank my wife and children for allowing me to have this indulgence."

2015Cai Q, Turner BD, Sheng D, Sloan S, 'The kinetics of fluoride sorption by zeolite: Effects of cadmium, barium and manganese', Journal of Contaminant Hydrology, 177-178 136-147 (2015)

Industrial wastewaters often consist of a complex chemical cocktail with treatment of target contaminants complicated by adverse chemical reactions. The impact of metal ions (Cd2 +, Ba2 + and Mn2 +) on the kinetics of fluoride removal from solution by natural zeolite was investigated. In order to better understand the kinetics, the pseudo-second order (PSO), Hill (Hill 4 and Hill 5) and intra-particle diffusion (IPD) models were applied. Model fitting was compared using the Akaike Information Criterion (AIC) and the Schwarz Bayesian Information Criterion (BIC). The Hill models (Hill 4 and Hill 5) were found to be superior in describing the fluoride removal processes due to the sigmoidal nature of the kinetics. Results indicate that the presence of Mn (100 mg L- 1) and Cd (100 mg L- 1) respectively increases the rate of fluoride sorption by a factor of ~ 28.3 and ~ 10.9, the maximum sorption capacity is increased by ~ 2.2 and ~ 1.7. The presence of Ba (100 mg L- 1) initially inhibited fluoride removal and very poor fits were obtained for all models. Fitting was best described with a biphasic sigmoidal model with the degree of inhibition decreasing with increasing temperature suggesting that at least two processes are involved with fluoride sorption onto natural zeolite in the presence of Ba.

2015Lu M, Wang S, Sloan SW, Sheng D, Xie K, 'Nonlinear consolidation of vertical drains with coupled radial-vertical flow considering well resistance', Geotextiles and Geomembranes, 43 182-189 (2015)

The consolidation behavior of ground with vertical drains is known to be greatly affected by the finite permeability of the sand drains, also called the effect of well resistance. However, up to now, no analytical methods have been reported for evaluating this effect on the nonlinear consolidation behavior of vertical drains. In this paper, by considering the nonlinear compressibility and permeability of soil during consolidation, the effect of well resistance was incorporated into the derivation of the equations that govern the nonlinear consolidation of a vertical drain with coupled radial-vertical flow. In addition, the smear effect was considered by assuming three decay patterns for the radial permeability coefficients of the soil toward the sand drain in the smeared zone. After obtaining the governing equations, a simplified analytical solution is derived for a general time-variable surcharge loading. Based on the general solution obtained, detailed solutions are provided for three special types of loading schemes: constant loading, single-stage loading, and multi-stage loading. The validity of the solution is verified by reducing it to several special cases and comparing these to existing solutions. Finally, the effect of the well resistance, the ratios of the compression index to the radial and vertical permeability indices, various loading schemes, and various variation patterns of the radial permeability coefficient of the soil in the smeared soil zone are investigated using parametric analysis.

2015Ding Y, Huang W, Sheng D, Sloan SW, 'Numerical study on finite element implementation of hypoplastic models', Computers and Geotechnics, 68 78-90 (2015)

A comprehensive numerical study on finite element implementation of hypoplastic models is presented. Two crucial aspects, local integration of the constitutive equations (the local problem) and forming tangent operators for Newton-Raphson iteration (the global problem), are investigated. For solving the local problem, different integration algorithms, including explicit and implicit methods, are examined using tri-axial compression tests and incremental stress response envelopes, as well as typical boundary value problems. For solving global problems, three different ways of generating the tangent operator are compared. The numerical evidences indicate that, in terms of accuracy, efficiency and robustness, explicit methods with substepping and error control are the best choices for constitutive integration of hypoplastic models while the so-called continuum tangent operators have certain advantages over two other types of numerically-generated consistent tangent operators.

2015Zhou A, Sheng D, 'An advanced hydro-mechanical constitutive model for unsaturated soils with different initial densities', Computers and Geotechnics, 63 46-66 (2015)

This paper presents an advanced constitutive model for unsaturated soils, using Bishop's effective stress (s') and the effective degree of saturation (Se) as two fundamental constitutive variables in the proposed constitutive model. A sub-loading surface and a unified hardening parameter (H) are introduced into the s'-Se modelling framework to interpret the effects of initial density on coupled hydro-mechanical behaviour of compacted soils. Compared with existing models in the literature, the main advantage of the proposed model that it is capable of modelling hydro-mechanical behaviour of unsaturated soils compacted to different initial densities, such as the dependence of loading-collapse volume on initial void ratio and density effect on the shearing-induced saturation change. The proposed model requires 13 material parameters, all of which can be calibrated through conventional laboratory tests. Numerical studies are conducted to assess the performance of the model for a hypothetical soil under two typical hydro-mechanical loading scenarios. The proposed advanced unsaturated soil model is then validated against a number of experimental results for both isotropic and triaxial conditions reported in the literature.

This paper presents an advanced constitutive model for unsaturated soil based on sub-loading surface plasticity. The proposed model is capable of modelling typical hydro-mechanical behaviour of soils compacted to different initial densities. Bishop's effective stress and the effective degree of saturation are selected as two fundamental constitutive variables in the proposed constitutive model. A sub-loading surface and a unified hardening parameter are introduced into the stress-saturation modelling framework to interpret the effects of initial density on hydro-mechanical behaviour of compacted soils.

2015Zhang X, Sheng D, Kouretzis GP, Krabbenhoft K, Sloan SW, 'Numerical investigation of the cylinder movement in granular matter', Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 91 (2015)

We investigate numerically the mechanisms governing horizontal dragging of a rigid cylinder buried inside granular matter, with particular emphasis on enumerating drag and lift forces that resist cylinder movement. The recently proposed particle finite element method is employed, which combines the robustness of classical continuum mechanics formulations in terms of representing complex aspects of the material constitutive behavior, with the effectiveness of discrete element methods in simulating ultralarge deformation problems. The investigation focuses on the effect of embedment depth, cylinder roughness, granular matter macromechanical properties, and of the magnitude of the cylinder's horizontal displacement on the amplitude of the resisting forces, which are discussed in light of published experimental data. Interpretation of the results provides insight on how the material flow around the cylinder affects the developing resistance, and a mechanism is proposed to describe the development of a steady-state drag force at large horizontal movements of the cylinder.

2015Yang C, Sheng D, Carter JP, Sloan SW, 'Modelling the plastic anisotropy of Lower Cromer Till', Computers and Geotechnics, 69 22-37 (2015)

Experimental data on Lower Cromer Till (LCT), a sandy silty-clay, are re-evaluated enabling a study on the effects of plastic anisotropy of soil fabric. The results of virgin constant stress ratio consolidation tests reveal that an equilibrium state is achieved and maintained under any specific radial loading path, with characteristics of a unique anisotropic fabric and a unique straining mode. The inclination of the plastic dilatancy and the yield surface from the hydrostatic axis provides a means of quantifying this equilibrium state of the soil fabric. A unique fabric anisotropy at critical state is naturally obtained. Rotational hardening laws are then proposed to quantify the changes in plastic anisotropy of soil fabric for all stress ranges. Constitutive relations are formulated within the framework of Critical Sate Soil Mechanics, with a non-associated flow rule logically determined from experiments. The proposed rotational hardening laws have been systematically validated against a large bank of laboratory tests on LCT samples, covering a variety of deposition conditions, stress histories, and overconsolidation ratios. Comparisons illustrate the feasibility and efficiency of the proposed framework in describing the plastic anisotropy of LCT, which may suggest possible application to other types of clays.

In this paper, an actual landslide process that occurred in Southern China is simulated by a continuum approach, the particle finite element method (PFEM). The PFEM attempts to solve the boundary-value problems in the framework of solid mechanics, satisfying the governing equations including momentum conservation, displacement-strain relation, constitutive relation as well as the frictional contact between the sliding mass and the slip surface. To warrant the convergence behaviour of solutions, the problem is formulated as a mathematical programming problem, while the particle finite element procedure is employed to tackle the issues of mesh distortion and free-surface evolution. The whole procedure of the landslide, from initiation, sliding to deposition, is successfully reproduced by the continuum approach. It is shown that the density of the mass has little influence on the sliding process in the current landslide, whereas both the geometry and the roughness of the slip surface play important roles. Comparative studies are also conducted where a satisfactory agreement is obtained.

This study presents a simple approach to modelling the effect of temperature on the soil-water retention curves (SWRCs) of deformable soils and takes into consideration the following two aspects: (1) the effect of temperature on the liquid-gas interfacial tension and (2) temperature-induced deformation of the soil skeleton. The first aspect, the temperature effect, can be modelled using an equation proposed by Grant and Salehzadeh [18], but the second aspect is generally neglected in the literature. To quantify the thermo-hydro-mechanical (THM) deformation of unsaturated soils (i.e., the second aspect mentioned above), a simple volume change equation, referred to as the non-isothermal SFG volumetric equation, is proposed on the basis of the original SFG framework [37]. A three-dimensional THM yield surface in the space of net mean stress, suction and temperature is presented here. The proposed volume change equation is integrated into the non-isothermal SWRC by means of a simple hydro-mechanical coupling law [38]. The performance of the non-isothermal SFG volumetric equation and the non-isothermal SWRC equation is investigated through several numerical examples. A number of experimental results reported in the literature are employed to confirm the validity of the proposed non-isothermal SFG volume change equation and the non-isothermal SWRC equation. © 2013 Elsevier Ltd.

2014Kouretzis GP, Sheng D, Wang D, 'Numerical simulation of cone penetration testing using a new critical state constitutive model for sand', Computers and Geotechnics, 56 50-60 (2014) [C1]

A new perspective on the numerical simulation of cone penetration in sand is presented, based on an enhanced critical state model implemented in an explicit-integration finite element code. Its main advantage, compared to similar studies employing simpler soil models, is that sand compressibility can be described with a single set of model parameters, irrespective of the stress level and the sand relative density. Calibration is based on back-analysis of published centrifuge experiments, while results of the methodology are also compared against independent tests. Additional analyses are performed to investigate sand state effects on cone penetration resistance, in comparison with empirical expressions from the literature. © 2013 Elsevier Ltd.

Thermo-Hydro-Mechanical (THM) coupling processes in unsaturated soils are very important in both theoretical researches and engineering applications. A coupled formulation based on hybrid mixture theory is derived to model the THM coupling behavior of unsaturated soils. The free-energy and dissipative functions for different phases are derived from Taylor's series expansions. Constitutive relations for THMcoupled behaviors of unsaturated soils, which include deformation, entropy change, fluid flow, heat conduction, and dynamic compatibility conditions on the interfaces, are then established. The number of field equations is shown to be equal to the number of unknown variables; thus, a closure of this coupling problem is established. In addition to modifications of the physical conservation equations with coupling effect terms, the constitutive equations, which consider the coupling between elastoplastic deformation of the soil skeleton, fluid flow, and heat transfer, are also derived. © 2014 The Chinese Society of Theoretical and Applied Mechanics; Institute of Mechanics, Chinese Academy of Sciences and Springer-Verlag Berlin Heidelberg.

A simple approach is proposed to quantify the effect of the initial void ratio on the relative coefficient of permeability for unsaturated soils based on the incremental relationship between the degree of saturation and the initial void ratio and the prediction of the permeability function for unsaturated soils by use of the soil-water characteristic curve (SWCC). For a given soil and the SWCC equation, only one additional parameter is introduced, which can be conveniently calibrated by the conventional SWCC tests. The relative coefficient of permeability for the same soil with different initial void ratios can be predicted by this approach. The proposed approach is validated through experimental data from the literatures in which both the SWCCs and the coefficients of permeability with different initial void ratios are measured.

The problem of granular column collapse is investigated by means of an axisymmetric version of the particle finite element method (PFEM). The granular medium is represented by a simple rate-independent plasticity model and the frictional contact between the granular flow and its rigid basal surface is accounted for. In the version of the PFEM developed for this study, the governing equations of the boundary value problem are cast in terms of an optimization problem and solved using mathematical programming tools. The agreement between model and experiment is generally satisfactory, quantitatively as well as qualitatively. However, the friction angle of the granular material, as well as the exact interface conditions between the base and granular material, are shown to have a relatively significant influence on the results. © 2014 Springer-Verlag Berlin Heidelberg.

Numerical simulation of cone penetration in sand is performed by means of a computationally efficient critical state model implemented in an explicit-integration finite element code. Its main advantage, compared to other published studies employing simpler soil models such as the Drucker-Prager, is that sand compressibility can be described with a single set of model parameters, irrespective of the stress level and the sand relative density.

This paper presents a numerical study of shear localization in granular materials based on a discrete element method. The plane Couette shear test is proposed for this purpose. A numerical model is established to simulate the test. With the flexible side boundaries, it is demonstrated that the plane Couette shear state can be achieved within a granular sample of limited length, and a shear band parallel to the shear direction can be obtained. Numerical results are also presented to show the formation and the development of the shear band. A homogenization procedure is employed for presenting the variation of the field variables such as stress components, the couple stress, the void ratio and the grain rotation. The evolution and the spatial distribution of these quantities are qualitatively in accordance with the Cosserat continuum model predictions. The numerical results also indicate that the Cosserat effect plays a vital role in shear localization zone. © 2014 Springer-Verlag Berlin Heidelberg.

This note explores the influence of environmental effects, as those induced by cyclic changes in relative humidity, on the degradation of the shear strength parameters in Lilla claystone, a low-porosity clayey rock from northern Spain. The results of a comprehensive experimental programme, combining long-term relative humidity cycling tests with saturated direct shear tests, are described. A continuous monitoring of the evolution of volumetric strain during the previous relative humidity cycling is used to evaluate the swelling behaviour of the rock. Both undisturbed and degraded specimens are subjected to shearing at saturated conditions to determine the peak and post-rupture shear strength envelopes. The effects on rock brittleness and dilation angle are also analysed. Shear strength shows a strong dependence on the history of relative humidity cycling. In particular, the evolution of the peak shear strength parameters (c' and ø) seem to be related to the accumulated irreversible strains developed during each cycle. A damage law, recently proposed by the authors, is used to represent the progressive degradation of the shear strength parameters as a function of the accumulated irreversible strains.

An alternative approach is developed in order to estimate the hydraulic conductivity of soft fine grained soils, based on numerical simulation of the full penetration and dissipation process for piezocones. Unlike previous methods of analysis, the process of penetration and dissipation has been explicitly simulated, thus eliminating several of the simplifications inherent in existing interpretation methods such as geometric approximations, predefined stress fields or neglecting material compressibility. The presented method is not established upon a particular set of data leading to limited applicability, but is rather developed using a more general approach and can be extended to other datasets if intended. Given the time to 50% consolidation and a number of influencing soil parameters, a single estimate of the soil horizontal permeability can be obtained via a single-run piezocone sounding using pore pressure measurements taken at the shoulder filter element (u2) located immediately behind the cone. The proposed interpretation method embodies many of the key parameters (namely the soil shear strength, soil rigidity, and soil confining stresses) likely to influence the soil behaviour and thus the parameter to be interpreted. Numerical analyses demonstrated that the rate of dissipation increases as the soil rigidity or the soil confining pressure increases, which is a consequence of higher excess pore pressure gradient at higher depths or at larger rigidities. The method, which involves a new excess pore pressure normalisation technique, is applicable to both monotonic and dilative dissipation data. The proposed interpretation method is compared to a series of experimental data including two recent field tests. Although the method was calibrated against only a select few cases, its applicability to a wide range of clayey soils was verified.

2013Sheng D, Zhou A, 'Unsaturated soil mechanics: Pitfalls in fundamental principles and engineering relevance', 5th China-Japan Geotechnical Symposium, 30-48 (2013)

The last two to three decades have seen significant advances in the mechanics of unsaturated soils. It is now widely recognized that the fundamental principles in soil mechanics should cover both saturated and unsaturated soils. Nevertheless, there is still a great deal of uncertainties amongst the geotechnical community about how well-established soil mechanics principles for saturated soils can be extended to unsaturated soils. There is sometimes even uncertainty about the necessity of such extension in engineering practice. This paper discusses some common pitfalls related to the fundamental principles that govern the volume change, shear strength and hydro-mechanical behaviour of unsaturated soils. It also discusses the relevance of these principles in engineering practice, in attempt to answer some of the critical questions that are often raised in the geotechnical community.

2013Cai G, Zhou A, Sheng D, 'Permeability function for unsaturated soils with different initial densities', Canadian Geotechnical Journal, 51 1456-1467 (2013)

This study proposes an approach to simulate the effects of initial density on the relative coefficient of permeability for unsaturated soils. The density-dependent permeability function is derived based on (i) an incremental relationship between the degree of saturation and the initial void ratio with various suctions and (ii) the relationship between the permeability function and the soil-water retention curve (SWRC). Only one additional parameter is required in the proposed function, which can be calibrated using a conventional SWRC test. A number of test results in the literature are employed to validate the proposed density-dependent permeability function, and the model predictions indicate good agreement with the experimental data in the literature.

2013Sheng D, Zhang S, Yu Z, Zhang J, 'Assessing frost susceptibility of soils using PCHeave', Cold Regions Science and Technology, 95 27-38 (2013) [C1]

This paper first presents a simple frost heave model. Frost heave is assumed to be caused by the formation of ice lenses in a freezing soil. The formation of ice lenses is governed by the Clapeyron equation of thermodynamics and relies on the existence of a frozen fringe between the frozen and unfrozen zones. Both unfrozen water and ice co-exist in pores of the frozen fringe. The suction at the water-ice interface is the driving force for the water flow that feeds the growth of the ice lens. The initiation of a new ice lens is governed by a simple effective stress concept. The frost heave model contains only a few soil parameters and can be used to compute frost heave and frost penetration in stratified soil profiles. The second part of the paper illustrates the application of the frost heave model in assessing the frost susceptibility of different soils. It is shown that the frost susceptibility of a soil must be assessed together with environmental conditions such as overburden pressure, temperature gradient, cooling rate and the depth of groundwater table. A soil that is only mildly susceptible to frost according to classification can still generate a significant amount of heave or heaving pressure under favourable environmental conditions. © 2013 Elsevier B.V.

The presence of a weak interlayer has usually an adverse effect on the slope stability. However, the rotational failure mechanism in the conventional upper bound limit analysis cannot rationally describe the sliding of the failure mass along the weak interlayer. Therefore, a new failure mechanism was proposed in this study to evaluate the stability of slopes with weak interlayers using the upper bound limit analysis and the associated factor of safety was determined by the shear strength reduction technique. The new failure mechanism is comprised of rigid blocks undergoing rotational or translational movements, instead of the rotational movement in the conventional failure mechanism. It has also been extended to the stability analysis of slopes in presence of stabilizing piles and pore water pressures. Case studies were carried out on actual slopes with weak interlayers. The proposed rotational-translational failure mechanism was verified by the shear strength reduction finite element method (SSRFEM). Comparisons demonstrate the reliability of limit analysis method with the proposed rotational-translational failure mechanism for slopes with weak interlayers and therefore it can be used as a simple evaluation method for the engineering design. © 2013 Elsevier Ltd.

A large-deformation numerical methodology is applied to simulate the interaction effects for a pipeline installed in a trench backfilled with loosely deposited dry sand, focusing on shallow buried pipelines subjected to lateral displacements relative to the surrounding soil. Based on the backfill-pipeline deformation mode under shallow embedment conditions, described in previous experimental studies, analyses are performed while considering only the critical state shear strength parameters of the backfill. The numerical methodology is validated against experimental full-scale test measurements from the literature, for pipelines buried in uniform dry loose and medium sand. Parametric analyses are performed to generate approximate formulas and charts for calculating (i) the maximum force on the pipeline and (ii) the minimum trench dimensions to eliminate interaction with the surrounding natural ground. Application of the proposed approach in the prediction of independent full-scale test results for a pipeline embedded in a shallow trench demonstrates its effectiveness, and underlines the effect of trench dimensioning on the response of the pipeline. © 2013 Elsevier Ltd.

A version of the Particle Finite Element Method applicable to geomechanics applications is presented. A simple rigid-plastic material model is adopted and the governing equations are cast in terms of a variational principle which facilitates a straightforward solution via mathematical programming techniques. In addition, frictional contact between rigid and deformable solids is accounted for using an approach previously developed for discrete element simulations. The capabilities of the scheme is demonstrated on a range of quasi-static and dynamic problems involving very large deformations. © 2013 Elsevier Ltd.

2013Yang C, Sheng D, Carter JP, 'Stochastic analysis of hydraulic hysteresis in multi-layer unsaturated soil covers under random flux boundary conditions', Geotechnical Special Publication, 542-554 (2013) [C1]

The effect of hydraulic hysteresis inherent in soil water characteristic curves is explored stochastically in seepage analysis of engineered soil covers. A multi-layer soil cover with random top boundary flux conditions is simulated with the First Order Second Moment method. Water inflow and outflow at the top boundary are chosen as two random variables. The capillary barrier mechanism is taken into account, and the breakthrough hydraulic head at the bottom boundary of the soil cover is adopted as the performance function. Results show that the hysteretic hydraulic model predicts a more conservative result than does the traditional nonhysteretic hydraulic model when simulating seepage in unsaturated, multi-layer soil covers. The dependence of the soil cover performance on its exterior environment during construction is also identified, with a relatively arid season significantly improving the soil cover's functionality. Furthermore, multi-layer soil covers with a proper selection of geotechnical materials provide better performance than a single layer of soil cover of the same thickness. The importance of hydraulic hysteresis in soil covers subjected to alternative climatic actions is emphasized. © 2013 American Society of Civil Engineers.

2013Sheng D, Cui L, Ansari Y, 'Interpretation of cone factor in undrained soils via full-penetration finite-element analysis', International Journal of Geomechanics, 13 745-753 (2013) [C1]

The cone penetration test is widely used to interpret the undrained shear strength of soil. The interpretation methods are commonly based on bearing capacity, cavity expansion, or strain-path methods. In this paper, the cone penetration test is analyzed using the large deformation FEMand contact mechanics. The full penetration process from the ground surface is modeled. The three-parameter Tresca model is used to represent the undrained soil behavior in a total stress analysis, to derive a cone factor equation for interpretation of the undrained shear strength. This equation is then compared with existing solutions in the literature as well as experimental data. The complexities that arise in more sophisticated soil models are elaborated in an effective stress analysis using the Modified Cam Clay model. © 2013 American Society of Civil Engineers.

This paper presents an alternative approach for interpreting unsaturated soil behaviour. In this approach, all constitutive laws are built in the space of stress versus degree of saturation. A new volume change equation is proposed in terms of stress and degree of saturation, to give a better explanation to the non-linear change of soil compressibility under constant suctions. The soil compression index is assumed to be a function of the effective degree of saturation. The yield surface is established in the plane of the effective degree of saturation and the Bishop effective stress. The proposed model is then validated against a variety of experimental data in literature. © 2012 American Society of Civil Engineers.

Based on a micropolar (Cosserat) continuum model, the formation of shear localization in granular materials is studied analytically and numerically. The possibility of shear localization in a uniformly deforming granular body is studied as a bifurcation problem. The analysis shows that shear bifurcation on the constitutive model level is suppressed in a micropolar continuum approach. Numerical studies are presented to show that the development of shear localization is a result of initial imperfection which exists inevitably in granular bodies. © Institute of Materials Engineering Australasia Ltd 2005.

Structured soils exhibit an apparent non-linear normal compression line in the semi-log compression plane, which dominates the difference in the mechanical behaviour between structured soils and their reconstituted counterparts. The effect of soil structure is investigated via the change of compression stiffness with structure degradation. A differential expression of the normal compression line is then established and applied to a large number of different types of soil. Satisfactory results are obtained, illustrating the validity and applicability of the proposed approach. © 2015 Taylor & Francis Group, London.

The plastic anisotropy of reconstituted soft soils is described from the compression behaviour observed during radial loading paths in stress space. A unique relationship is established between the orientation of the yield surface and the corresponding normal compression line, which indicates that a stabilized fabric is maintained under continuous loading along radial stress paths. The equilibrium orientation angle of the plastic potential surface is obtained explicitly. A new rotational hardening law is proposed by considering the dependence of the evolution of anisotropic fabric with the current stress condition and plastic strain. An elastoplastic constitutive model for anisotropic soil is formulated within the framework of Critical State Soil Mechanics. Validation with experimental data and predictions from other models demonstrate the feasibility of the basic concept and the capacity of the proposed new model. © 2014 American Society of Civil Engineers.

2014Zhang X, Krabbenhoft K, Sheng D, 'Particle finite element simulation of Granular media', Applied Mechanics and Materials (2014) [E1]

Despite their ubiquity, the simulation of granular materials poses a continuing challenge in computational mechanics, as these materials can behave like solid, liquid and gas. In this paper, a recently developed version of the Particle Finite Element Method is applied for analyzing the behaviour of granular media under very large deformations. Both quasi-static and dynamic problems are considered. It is shown that this continuum approach is applicable to general large deformation problems of granular materials, including liquid-like flows. © (2014) Trans Tech Publications, Switzerland.

2014Ansari Y, Kouretzis GP, Sheng D, 'Coupled finite element analysis of partially embedded offshore pipelines during vertical penetration', Applied Mechanics and Materials (2014) [E1]

Diverse vertical embedment response is observed for partially embedded pipelines when experimentally tested under similar initial and boundary conditions. Although vertical resistance of pipelines is presented through simple analytical solutions, a number of factors contribute to complications in implementing these theories into practice. The objectives of this research is to provide a more detailed investigation on the vertical embedment for the partially-embedded pipelines (PEPs) using a coupled large deformation finite element (CLDFE) analysis with contact. A modified Cam Clay (MCC) model represents the elastoplastic response of the soil. The model of pipeline embedment investigates the effect of drainage condition on heave forming with respect to rate of penetration. Besides, effect of frictional contact on the heave development and wedging effect is investigated and design-related considerations are proposed. It is shown that depending on the rate of pipeline penetration and soil consolidation rate, the pipeline penetration response can be categorised as undrained, partially drained or fully drained. © (2014) Trans Tech Publications, Switzerland.

2014Nazem M, Carter JP, Airey DW, 'Arbitrary Lagrangian-Eulerian method for non-linear problems of geomechanics', IOP Conference Series: Materials Science and Engineering (2014)

In many geotechnical problems it is vital to consider the geometrical non-linearity caused by large deformation in order to capture a more realistic model of the true behaviour. The solutions so obtained should then be more accurate and reliable, which should ultimately lead to cheaper and safer design. The Arbitrary Lagrangian-Eulerian (ALE) method originated from fluid mechanics, but has now been well established for solving large deformation problems in geomechanics. This paper provides an overview of the ALE method and its challenges in tackling problems involving non-linearities due to material behaviour, large deformation, changing boundary conditions and time-dependency, including material rate effects and inertia effects in dynamic loading applications. Important aspects of ALE implementation into a finite element framework will also be discussed. This method is then employed to solve some interesting and challenging geotechnical problems such as the dynamic bearing capacity of footings on soft soils, consolidation of a soil layer under a footing, and the modelling of dynamic penetration of objects into soil layers.
