摘要
Abstract
Combined with a concrete arch dam and present design specifications for arch dams, a dynamic anti-sliding stability analysis method based on the safety index criterion for abutment fractured rock mass is presented. Taking comprehensive advantages of the finite element method and the rigid limit equilibrium method, and taking into account the uncertainties of different values of cohesion c and internal of friction coefficient/with large differences, this analysis method defines the anti-sliding stability safety index to evaluate anti-sliding stability safety degree of the abutment rock mass. And the anti-sliding stability safety index changes with the change of cohesive force's and friction's occupying weight. This method both considers coupling effect between the abutment rock mass and the dam body, and can reflect real behavior of the arch dam system. Based on a high concrete arch dam engineering, the aseismic stability of the abutment fractured rock mass is analyzed. The results show that the method has high practical value.关键词
