| 摘 要： | 确定工程岩体的力学特性参数是一项艰巨而复杂的工作 ,RFPA程序无疑为我们提供了一条方便而可行的途径。但是 ,在进行数值模拟实验时 ,由于各单元的参数是按韦伯分布赋值的 ,所以其前处理过程较其它有限元程序复杂得多。本文针对前处理过程几个最重要的影响因素 ,进行了系统的总结和分析 ,以期能更好地为岩石力学的实际应用服务

| Abstract: | It is a difficult thing to determine the mechanical parameters of engineering rock masses However,the program RFPA can offer us a convenient and practical method When using RFPA for numerical simulation,its preprocessing is much more complex than other methods of finite element because the values of every element's parameters are assigned according to Weibull distribution. This paper aims to systematically summarize and analyze the major factors to affect the preprocessing so as to give better service to rock mechanics and engineering |
