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。In this paper, effective stress for double 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.
