土石坝地震反应方法解析
|
摘要
我国地震区域分布十分广泛,地震频繁而且强烈,已建和拟建的土石坝中,有不少都处于地震高烈度区。一旦发生地震,大坝遭受破坏将直接威胁下游人民生命财产安全和各种社会活动的正常进行,造成大的经济损失。所以地震越来越成为人们关注的对象,抗震减灾也成为结构设计中必要环节。本文将土石坝动力计算的几种方法进行了总结,为土石坝的动力计算方法的选择提供了依据。
China has lots of broad seismic zones and earthquakes occur frequently and severely. Many of the dams constructed and proposed are located in the high intensity seismic zones. Once the earthquakes occur,the damages to the dams will be a direct threat to the safety of downstream people,their properties and various social activities as well as the social fortune. Therefore,the earthquake has increasingly become people's focus and seismic disaster reduction has become an essential purpose in the structural design of dams. The author sums up a variety of dynamic calculation methods for dam construction.
