基于粘弹性边界在重力坝动力分析中的应用
Application of Viscoelastic Boundary in Dynamic Analysis of Gravity Dam
摘要
Abstract
In the dynamic analysis of gravity dams,selecting appropriate artificial boundary conditions can accurately simulate the propagation characteristics of waves at the boundary position of the model foundation,and improve the accuracy of numerical analysis results.Taking Zangmu gravity dam in Xizang as an example,the dynamic response law of gravity dam under different conditions is compared and analyzed by using the finite element method.This paper analyzes and compares two aspects:different boundary conditions and different input seismic motions.The results show that the viscoelastic boundary conditions can accurately simulate the response of gravity dams under seismic dynamic action compared with the traditional fixed boundary conditions.关键词
