摘要
基于等价结点力法，将地震动模拟为平稳高斯过滤白噪声过程，通过随机地震反应分析，建立一种土石坝地震平均永久变形有效算法，然后对瀑布沟土石坝进行数值计算，结果符合一般规律．
The earthquake excitation is simulated as stationary Gaussian filter white-noiseprocess, on the basis of equivalent nodal force method and stochastic seismic response analysis, the paper presents a method for analysis of permanent deformation of embankmemt damdue to stochastic seismic excitation. and then conducts numerical calculation for Pubugoembankment dam. The calculated results are in accordance with the law of observation.
