To develop methods and software that can efficiently assess the bearing capacity and factor of safety of civil and military infrastructure such as tunnels, roads, bunkers and trenchers.

Emphasis will be placed on robust computational schemes for three-dimensional problems and complex ground conditions, where current procedures are often inadequate.

Competitive advantage

  • Calculation of bearing capacities in a single step
  • Straightforward computation of safety factors
  • Shakedown analysis capabilities for cyclic or variable loadings
  • Robust FE core and automatic mesh adaptivity
  • Unparalleled efficiency and speed of GPUaccelerated parallel solvers

Successful applications of research

Accurate stability evaluation for a broad range of geotechnical structures, including:

  • Foundations and piles
  • Anchor systems
  • Supported and unsupported excavations and slopes, underground openings and tunnels

Impact

  • Safer and cost-efficient design of infrastructure
  • Reliable prediction of ultimate loads and factors of safety for complex ground and loading conditions
  • Treating uncertainty in ground parameters via stochastic analysis

Capabilities and facilities

  • Rigorous lower and upper bounds on ultimate loads and factors of safety
  • Staged construction and integrated preliminary analyses
  • Variety of soil and rock material models
  • Automatic adaptive mesh refinement
