    • Abstract
  • The effective stress analysis is an important issue in the study of poroelastic formulations that couple solid deformations with fluid. Based on the effective stress law for isotropic multi-porosity and anisotropy double porous media law, this paper developed anisotropic triple porous media effective stress law. Then, it was simplified as anisotropic double porous media effective stress law, which was proved to be feasible and rational. Anisotropic multi-porosity media effective stress law is developed on the basis of anisotropic triple porous media effective stress law. The mathematical expression of anisotropic multi-porosity media effective stress law depends on the decomposition of loadings on multi-porosity media.
