边坡稳定模糊随机可靠度分析
Analysis of fuzzy-random reliability of slope stability
【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.
