有效应力在研究流固耦合变形问题有其重要的地位。该文通过对各向同性多重孔隙介质有效应力定律和各向异性双重孔隙介质有效应力定律分析,推导各向异性三重孔隙介质有效应力定律,并对所建各向异性三重孔隙介质有效应力定律简化为已经发表的各向异性双重孔隙介质有效定律,证明模型的存在性、合理性。在各向异性三重孔隙介质有效应力定律的基础上推导各向异性多重孔隙介质有效应力定律。各向异性多重孔隙介质有效应力定律的表达式取决于对多重孔隙介质受力的分解。
Effective stress in the study of fluid-solid coupling deformation has its important position. In this paper, the effective stress laws of isotropic triple porosity porous media are derived by analyzing the effective stress laws of isotropic multiple porous media and the effective stress laws of anisotropic dual porosity media. The effective stress laws of anisotropic triple porosity porous media are simplified For the published effective anisotropic double-porosity medium law, to prove the existence of the model, the rationality. The effective stress law of anisotropic multiple porous media is derived based on the law of effective stress in anisotropic triple porosity media. The expression of the law of effective stress for an anisotropic multiple porous media depends on the decomposition of stress in multiple porous media.
