摘要
本文基于三维随机有限元提出了结构点可靠度、失效模式的可靠度及整个结构体系的可靠度分别对随机变量的＂分布参数＂和＂极限状态方程参数＂的敏感性计算方法，并以一典型重力坝为例进行了计算，得出了若干有益的结论。
Based on 3-D SFEM, sensitivity (including distribution parameters and limit state function parameters) analysis of component reliability and failure mode reliability and whole system reliability is presented. A standard gravity dam taken as an example, some useful conclusions are given.
