Tunnelling

This project will focus on numerical analysis of plasticity problems for the stability of tunnel under static and seismic conditions. This will concentrate on the use of advanced numerical analyses for solutions of failure in both 2D and 3D using the elasto-plastic analysis and the limit analysis. A strategy for automatic mesh refinement is combined with the advanced numerical procedure. Effects of soil properties and tunnel geometries (i.e. single and twin tunnels) are the focus of this study.
