| Abstract: | 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. |
