摘　　要：F_(67)断层破碎带是新坝址区发育规模最大、工程地质特性最差的一条断层破碎带,其断层破碎带物理力学参数的选取直接制约工程可行性及后期运行安全性。文中对断层破碎带的具体地质条件进行了分析论述,并针对可研勘察阶段和技施阶段断层破碎带的物理力学性质进行了对比研究,提出破碎带岩体抗剪(断)强度指标适宜的建议值。F_(67) fault fracture zone is a fault fracture zone with the largest development scale and the worst engineering geological characteristics in the new dam site.The selection of physical and mechanical parameters of fault fracture zone directly affects the feasibility of the project and the later operation safety.In this paper,the specific geological conditions of the fault fracture zone are analyzed and discussed,and the physical and mechanical properties of the fault fracture zone are compared between the feasibility exploratory stage and the technical stage,and the appropriate recommended value of shear strength index of the rock mass in the fracture zone is put forward.
