Modularized numerical approach for coupled thermo-hydro-mechanical process of rock mass

Based on the infinitesimal deformation assumption, initiated from linearity momentum conservation, mass and energy conservation and also constitutive laws of rock mass, derived a set of thermo-hydro-mechanical coupling governing equations treated displace, pore pressure and temperature as unknown variables, these equations including deformation field equation, fluid flow and heat transfer equations. Then according to modularization idea, two main numerical modules were proposed and iterative implemented to solve the two different equations, and two coupling modules were executed for message deliver between two main modules, through which the solution of coupled thermo-hydro-mechanical processes was achieved, in the end, some suggestions for future research were given.
