摘要 
 针对裂隙岩体的力学参数选取问题，提出了一种两阶段评价方法.通过裂隙岩体力学参数的三维空间分布情况，评价其各向同性与各向异性状态，对两类情况采用不同的计算模型处理；采用Kolmogorov-Smirnov(K-S)检验法对力学参数的概率分布模型进行假设检验，对检验合格的试验数据分布进行置信区间选取，在给定的置信区间内获取计算参数.在某地下硐室工程中运用该方法进行了开挖模拟计算，计算位移与实测位移吻合较好.

Abstract：
A two-stage evaluation method was proposed to obtain the values of mechanical parameters of the fractured rock mass. The isotropy and anisotropy state of the fractured rock mass was evaluated through the three-dimensional distribution of mechanical parameters, and two types of calculation models were adopted respectively; the KolmogorovSmirnov (K-S) test was used in hypothesis testing of the probability distribution model of mechanical parameters, and the confidence interval of the data which has passed the hypothesis test was determined, so that calculated parameters could be obtained within the given confidence interval range. A case of excavation simulation for an underground chamber engineering project was conducted using this method. The result indicates that the calculated displacement values agree well with the measured values.
