摘　　要：通过对某水电站岩体抗剪强度试验成果,采用Hoek-Brown对该类结构面抗剪强度进行了预测分析,Hoek-Brown法预测结果与点群中心法的峰值强度平均值、残余强度平均值较为相近;同时采用线性、多项式等方式进行拟合,从拟合结果可知在一定的正应力条件下,结构面的抗剪强度不是直线型发展的,在结构面试验中一定要注意曲线所代表的参数选值和界定范围及环境。对结构面抗剪性能的预测及分析,可为类似试验工程提供借鉴。This article through to a hydropower station in geotechnical shear strength test results,the Hoek-Brown of the structural plane shear strength has carried on the forecast analysis,Hoek-Brown predicted results with the point group center method is relatively close to the average peak strength,residual strength of average. At the same time using linear and polynomial fitting in the form of normal stress from fitting results indicate that under certain conditions,the development of the structure of the shear strength is not linear,it is important to note that in the structural plane test curve represented by the parameter values and define the scope and the environment. The purpose of this paper is to forecast and analysis on the performance of structural plane shear,can be used for similar test engineering.
