Mathematical modeling of coupled T-H-M processes in rocks

The necessity of THM modeling appeared in the nineties within the framework of nuclear wastes storage in deep geological formations. Models have then been extended to include the effects of temperature on the mechanical and the hydraulic behavior of rocks (Rutqvist et al. 2001, Collin et al. 2002). Accurate description but also the implementation of such coupled phenomena still remains a challenge. After defining a THM model for partially saturated rocks, its implementation is described then compared to experimental results.
