The Coupled Thermo-Hydro-Mechanical Behavior of Saturated Fractured Solids

Abstract:

The stress equilibrium equation of anisotropic solids, coupled to the hydrodynamic seepage equation and heat transfer equation of saturated fractured rocks, are studied here based on the standard space of physical presentation, in which an new thermo-hydro-elastic model is induced. A set of uncoupled equation of heat and hydraulic propagations in anisotropic saturated fractured rocks is deduced. From them, two new phenomena of heat and hydraulic propagation are obtained, which are affected by both anisotropic subspaces of solids and thermo-mechanical and hydro-mechanical coupling coefficients. Based on these laws, we discuss the heat and hydraulic wave behaviour for isotropic solids.
