One of the most suitable ways under study for the disposal of high-level radioactive waste (HLW) is isolation in deep geological repositories.It is very important to research the thermo-hydromechanical (THM) coupled processes associated with an HLW disposal repository.Non-linear coupled equations, which are used to describe the THM coupled process and are suited to saturated-unsaturated porous media, are presented in this paper.A numerical method to solve these equations is put forward, and a finite element code is developed.This code is suited to the plane strain or axis-symmetry problem. Then this code is used to simulate the THM coupled process in the near field of an ideal disposal repository.The temperature vs.time, hydraulic head vs.time and stress vs.time results show that, in this assumed condition, the impact of temperature is very long (over 10000 a) and the impact of the water head is short (about 90 d).Since the stress is induced by temperature and hydraulic head in this condition, the impact time of stress is the same as that of temperature.The results show that THM coupled processes are very important in the safety analysis of an HLW deep geological disposal repository.
