| Abstract: | Based on the existed researches on the permeable behavior affected by thermal(T), hydrological(H), and mechanical(M)respectively and the experiments of single fracture rock sample under temperature and tectonic stresses, this paper analyzed synthetically the coupled THM processes in the fracture rock mass media. The paper makes a thorough study on aperture of rock joins, the number of open cracks after heating in rock mass, the fracture interconnectivity, tectonic stresses, and the dilation due to shear sliding. The tensor field of permeability in the fracture rock mass with coupled THM properties is derived. |
