本文对重力坝用二维有限单元法,按实际地震波和人工地震波的时程曲线对一系列的坝进行动力分析,在此基础上研究了重力坝在地震作用上的基本特性,探讨了重力坝的各种动力反应的大小及其变化情况。
In this paper, two-dimensional finite element method for gravity dam is used to analyze the dynamic behavior of a series of dams according to the time-history curve of actual seismic wave and artificial seismic wave. On this basis, the basic characteristics of gravity dam in earthquake action are studied. The size of the various dynamic response and its changes.
