Centre for Geotechnical Science and Engineering
Geoinfrastructure
The provision of transport and other service infrastructure is a priority of governments worldwide and is of critical importance to future prosperity. Indeed, to reduce traffic congestion, improve freight logistics and accommodate a rapidly growing population, it is predicted that hundreds of billions of dollars will spent over the next decade on rejuvenating ageing transport infrastructure in Australia alone. Due to the massive investment involved in constructing roads, railways, tunnels, ports and pipelines, even small percentage savings resulting from scientific research give large returns in absolute dollar terms. Research conducted in the Centre for Geotechnical Science and Engineering is providing engineers with new science-based tools for tackling these infrastructure problems, with a strong focus on the delivery of new procedures and software for quantifying risk, providing cost-effective design solutions, managing risk during construction, extending the life of ageing infrastructure, and maximizing the use of sustainable construction materials.

Unsaturated Soils Mechanics and Reactive Clays
The aim of this research is to provide new knowledge on the behaviour of unsaturated soils and reactive clays. Advanced laboratory and field testing on soils are complemented by microstructural investigations in order to correlate macroscale observations to soil structure.
Rock Mechanics
Read about hydromechanics of rock matrix, rock masses and rock discontinuities.
Soft Soil Engineering
This project provides detail on the project delivery methods adopted on the Pacific Highway upgrade as well as site characterisation, the Ballina Field Test Facilty and the Embankment Prediction Sympoisum.
Pipelines Crossing Geotechnically Challenging Environments
This project provides detail on physical and numerical modelling techniques employed by researchers at the Centre to improve analysis and design methods for pipelines on geographically challenging areas susceptible to ground movement.
Ground Improvement for Infrastructure on Problematic Soils
Read about the Centre's current research on ground improvement methods for soft problematic soils.
Failure of Soil and Rock Masses from Small to Large Scale
Read about research activities at the Centre, spanning from reduced scale to full scale, to observe and better understand soil and rock failure with the aim to transform design practice.
Rockfall Analysis
Read about the Centre's experimental testing on rock fall trajectories, rockfall in the mining environment as well as rock fall barrier testing.
Risk Assessment in Geotechnical Engineering
The Centre has developed probabilistic methods, where risk is explicitly quantified, enabling practicing engineers to better quantify uncertainty, ultimately resulting in decreased project construction costs.
