建立了随机动力非线性有限元法，对三峡重力坝下游面钢筋混凝土压力管道进行了动力可靠度计算，给出了其在地震作用下的可靠指标和失效概率
A nonlinear finite element method is established to calculate the dynamic reliability of the reinforced concrete pressure pipe downstream of the Three Gorges gravity dam. The reliability index and the probability of failure under earthquake are given
