Effective Stress Laws for Multi-Porosity Media
-
摘要: 通过对双重孔隙介质有效应力的研究,建立了多重孔隙介质条件下的有效应力定律,发现了有效应力定律的唯一性依赖于孔隙介质本构关系的假设,提出了多重孔隙介质有效应力定律的所有可能形式。Abstract: In this paper, the effective stress for multi-porosity elasticity model is presented by means of stress analysis for double porosity media elements. It is found that the effective stress law is not unique, it depends on the hypothesis of constitutive equations for multi-porosity media. Diversified effective stress laws for multi-porosity are developed.
