- Abstract
According to present deficiency of gravity retaining wall design method and considering the fuzzy uncertainties of the parameters of stochastic variables, first-order second-moment method (FOSM) is adopted to set up fuzzy random reliability analyzing model. By using decomposing theorem and by introducing cut set, fuzzy numbers were convened into a series of interval numbers and fuzzy random reliability computing technology was received. The major instability modes of gravity retaining walls are overturning and sliding. Two structural performance functions against overturning and sliding of gravity retaining walls were established and the fuzzy random variables were confirmed. Two kinds of invalid modes are calculated separately by the use of fuzzy random reliability computation method, which two fuzzy random reliability indexes and corresponding failure probabilities are obtained. Comparing the result of computation method with that of related literature, it is shows that obvious differences are between them. It is pointed out that structural performance function Z of the gravity retaining wall is assumed as normal distribution in related literature, which contributing to errors in the probability density function f(Z) in this treatment. The calculated results of fuzzy random reliability by adopting cut set way are conformed to reality better.
