Abstract

In deep geological disposal for high level radioactive waste, one of the most important factors is to study the thermo-hydraulic-mechanical (THM) behavior of natural barrier, that is, host rock during heat process and hydraulic environment change. In this paper, a program of finite element method called as SOFT, using finite element-finite difference method in soil–water-heat coupling problem has been developed to simulate the above-mentioned THM behavior of geological disposal based on a thermo-elasto-viscoplastic constitutive model. In order to verify the availability of the program, a real-scale field heating test reported by Gens et al. (2007) is simulated by the proposed THM-FEM program. The material parameters of the rock involved in the constitutive model are determined based on element tests for the rock. It is shown from the figures that the proposed program can well describe the THM behavior observed in the heating test such as temperature and excessive pore water pressure (EPWP).
