| 摘 要： | 考虑边坡稳定评价中存在的两种不确定性——模糊性和随机性，以模糊随机变量为基本变量，建立模糊随机功能函数和模糊随机极限方程，得到模糊可靠指标和模糊可靠度。本文给出模糊随机可靠度的计算方法，给出实例并与经典随机可靠度比较，得到更合理的结果。

| Abstract: | Considering two uncertainties, randomness and fuzziness, in slope stability assessment, and taking fuzzy random variables as basic variables, a slope fuzzy random failure function taking and a slope fuzzy random limit state equation is established. A methodology is presented so as to obtain the slope fuzzy reliability and reliability index. An example is given, and the results are compared with the current reliability assessment. |
