摘要
坝体在地震波作用下安全性是目前国内外学者比较关注的问题之一。利用ANSYS软件模拟对坝体作了静力分析、模态分析以及地震波作用下的时程分析,了解了岩石坝体的一些静力特性和结构动力特性。得到了一些地震波作用下坝体及附近地层岩石的位移、速度、加速度随时间变化的特征曲线,对坝体的设计、材料的选择以及基础深度的选择具有一定的意义。
The safety of dam bodies subjected to the seismic wave is one of the questions that concern domestic and international scholars at present. This paper highlights a static analysis and modal analysis of dam bodies using ANSYS software. The paper gives knowledge of static characteristics and structure motive force characteristics of the rock dam body. The acquired characteristic curves of displacement, speed and acceleration time change of dam bodies subjected to seismic wave and their nearby stratum assume a definite meaning for designing of dam body, the choice of foundation material, choice of foundation depth.
