本文以西部地区深厚覆盖层上土石坝的抗震设计分析为研究对象,采用有限元法模拟随机波作用,对不同坝高和不同覆盖层厚度条件下的土石坝进行了动力响应计算,分析了反应加速度和动应力变化特征。
In this paper, the seismic design analysis of earth-rockfill dam with deep overburden in western China is taken as the research object. The finite element method is used to simulate the stochastic wave. The dynamic response of earth-rockfill dam with different height of dam and different cover thickness is calculated. Acceleration and dynamic stress change characteristics.
