- 摘要： The theory and method are studied for anisotropic strength criteria of jointed rock mass, based on Mohr-Coulomb and Rankine criteria by introducing the persistence ratio and strength parameters of rock mass obtained from network simulation. The above theory and method are adopted to establish anisotropic strength criterion and make dynamic analysis for deep sliding surface of dam-rock foundation system. The analytical results show that the failure plane by anisotropic strength criterion cannot coincide with the maximum shear stress plane. It can improve the shortcoming of Mohr-Coulomb criterion for overestimating the material tensile strength of rock mass by combining Rankine and Mohr-Coulomb criteria. The strength criterion can simulate the failure characteristics of jointed rock mass reflected by relationship between resistance and response.
