| 摘要: |
| 讨论了随机-模糊处理方法在岩石力学指标统计分析中的应用，并对计算中诸如迭代精度、隶属函数的取值等关键问题进行了较深入地研究。结果表明，基于岩石样本力学参数的离散性中既包含随机不确定性，又包含模糊不确定性，采用随机 模糊处理方法优于其他常规的统计方法，从而为该方法在工程实践中的应用奠定了基础。 |

| Abstract: |
| In this paper，the application of random-fuzzy method to statistic analysis of mechanical parameters of rock samples was discussed,and some computation questions such as subordinate function's choice are studied deeply.The result indicates that the characteristic of rock and soil mechanic parameter not only has random character,but also shows ambiguity;random-fuzzy method is proved supperior to other common methods,and therefore establishes the base of application to engineerings. |
