摘 要：This paper aims to develop a thermo-hydro-mechanical coupling method of deformable porous media,and on this basis investigate the effect of steam injection on borehole stability. First,a thermo-hydro-mechanical coupling model for steam injection is developed by using continuum mechanics approach, based on the theories of solid mechanics,seepage mechanics and heat ***,an iterative solution method which uses standard Galerkin finite element method for spatial discretization and second order backward difference method for temporal
