边坡模糊随机可靠性分析的模糊点估计法
Fuzzy random reliability analysis of slope based on fuzzy point estimate method
摘要
Abstract
The fuzzy point estimate method of slope engineering reliability evaluation is presented based on the statistical moment point estimate method and fuzzy random theory. The slope stability limit state equation is transformed from fuzzy random set to normal random set, then the point estimation method is used to solve the slope reliability indexes. In view of the approximate distribution types for physico-mechanical parameters of rock mass, the normal fuzzy number, which is different from the normal number is used to do fuzzy random variable. By doing this, the physico-mechanical parameters are closer to its real distribution types. The fuzziness of various mechanical parameters is considered. The calculation results can reflect the true working condition of slope. A case study shows that the method has a higher calculation efficiency and reliable calculation results, and it is convenient in use; it also avoids the shortcomings of traditional methods. The method has great potential for slope reliability analysis of complex slope or functions for implicit expression; it provides a new way to slope reliability analysis and has a broad prospect of application.关键词
