摘要

利用一次二阶矩法，考虑可靠性分析模型中随机参数的模糊性，建立了模糊随机可靠性分析模型。利用分解定理，取一系列截集，将模糊数转换为一系列区间数进行运算，得到了一种模糊随机可靠度的计算方法。将该法应用到桩的可靠性分析中，实例表明，该方法是合理实用的。

Abstract

Considering the fuzzy uncertainties of the parameters of stochastic variables

a fuzzy stochastic reliability analysis model is derived based on first-order second-moment method (FOSM). By introducing ? cut set

fuzzy numbers are converted into a series of interval numbers; by use of which

fuzzy stochastic reliability is calculated. The proposed method is employed to the reliability analysis of pile foundation. Case study shows that this method is theoretically innovative and practically useful.
