The control equations for analyzing coupled thermo-hydro-mechanical phenomena in saturated-unsaturated porous media established by the author are described. Aiming at the axisymmetric model test for geological disposal of high-level radioactive nuclear waste and the parameters of material for analysis in Task-2 of DECOVALEX II
a numerical simulation for the coupled thermo-hydro-mechanical process in the buffer-rock system is carried out by using FEM code developed by the author. The distributions and changes of temperature
water content and contact stress in some parts in the buffer and the rock are investigated. Through comparing the simulation results and the results obtained by measuring and THAMES program
the different and the identical parts in three results are showed and the possible influence factors are pointed out. So it can be considered that the FEM code developed for simulation of coupled thermo-hydro-mechanical processes in geological disposal of nuclear waste is reliable and practicable.
