摘　　要：探讨了随机 模糊处理方法在岩石力学指标统计和岩组定量划分中的应用。文中对计算中的隶属函数取值及迭代方式进行了深入讨论。通过计算结果的比较分析 ,认为随机 模糊处理方法更符合实际 ,并优于其他方法。最后作者提出了岩组定性划分 岩石样本参数的随机 模糊统计分析 岩组定量划分及参数重新统计的分析程序。This paper inquires into application of random fuzzy method to statistic analysis of mechanical parameters of rock samples and quantitative dividing them into groups of rock mass. The stochastic uncertainty of mechanical parameters of rock samples is discussed. A presented random fuzzy method for processing of experimental data of the mechanical parameters of rock samples is improved. The authors place emphasis on discussion of choice of subjection function of rock samples in this paper. The result indicates that the values obtained with the random fuzzy method is more realistic and better than the conventional methods. Finally, the authors present analytic process: qualitative division of mechanical parameters of rock samples into groups of rock mass statistic computation of them by the random fuzzy method quantitative division of them into groups of rock mass.
