A Finite Element Analysis of the Thermo-Hydro-Mechanically Coupled Problem of a Cohesive Deposit Using a Thermo-Elasto-Viscoplastic Model

摘要

We propose a thermo-hydro-mechanically coupled finite element analysis method for clay with a thermo-elasto-viscoplastic model. The volume changes in soil particles and pore fluids are introduced into the analysis method. The instability of the problem is studied and a numerical simulation of the thermal consolidation is presented using the newly developed analysis method. It was confirmed that the analysis method can reproduce the thermal consolidation phenomenon well.
