摘要
本文分析了三峡工程基础岩体各类平直稍粗结构面29组抗剪强度成果,其中包括4组抗剪断强度(初剪强度),4组残余上限强度,4组残余下限强度,以及17组单点摩擦强度(复剪强度);论证了取建立在统计基础上的综合强度,作为平直稍粗结构面的剪切强度依据的合理性。
This paper analyzes shear strength results of 29 sets of various flat slightly rough structureplanes for foundation rock of Three Gorges Project. They include 4 sets of shear strength (intial shearstength), 4 sets of upper limited residual strength, 4 sets of lower limited residual strength and 17 sets of single point friction strength (repeated shear strength). And it is demonstrated that synthetical strength obtained by means of statistics can be regarded as the basis of shear strength for flat slightly rough structure plane.
