摘　　要：阐述了岩石材料的非匀质性特性,根据这种特性提出了对材料参数进行随机赋值方法。为了对非匀质类材料的弹塑性破裂过程进行数值模拟研究,必须在有限元计算中实现材料参数随机赋值。介绍了应用程序的结构与特点。给出了工程实例——不同形状巷道的破裂过程比较。The paper expounds the non - uniformity characteristics of rock material. According to this characteristics, the random assignment method for value of the material parameters is put forward. In order to study the numerical simulation for the elastic - plastic failure of non - uniformity materials, the random assignment for value of the material parameters in the finite element computation must be realized. The structure and distinguishing feature of the application program are introduced. The comparison between the failure process for three different shaped tunnels of the practical engineering examples are given.
