Analysis of the Fuzzy Reliability in Geotechnical Engineering Based on Choosing the Membership Functions
-
摘要: 目前岩土工程中模糊可靠度计算时隶属函数的选取还没有一个统一标准,针对这种现状进行研究,选取了三种具有代表性的隶属函数,并将其分别应用于岩土工程中的两种典型结构:地下连续墙和挡土墙,通过模糊可靠度的计算以及比较分析,得出如何选取优化隶属函数的有益结论,对工程应用具有实际的指导意义。Abstract: The fuzzy probability of two typical structures in geornechanics engineering, underground diaphragm wall and retaining wall, is calculated by three representational membership functions and a probability density function for the performance function. Then some useful conclusions on choosing the optimal membership function are obtained.
