考虑动水压力的土石坝三维动力反应分析
首发时间:2010-04-12
摘要:在以往的心墙土石坝动力反应分析中,一般不考虑动水压力对坝体的影响。目前一批300m级的高坝将在处于强震区的西南地区兴建,这些高土石坝的抗震性能是人们十分关注的重大问题。本文通过介绍一种考虑水体可压缩性的流固耦合法,并将其应用在某300m级高土石坝的动力反应分析中,并得出合理的坝体动力响应。

Dynamic Analysis for Rock-fill Dam Including
Abstract:In current investigation, related to the dynamic study of rock-fill dam-water-foundation problems are still limited. At present, a number of high rock-fill dams will be built in the southwestern region where most of them are located in strong earthquake area. The stability and security of dams under strong earthquake have become the major issues that the people are very concerned about. This paper provides a method that considers the interaction with the rock-fill dam-water-foundation system. Three dimension dynamic analyses is carried out about a rock-fill dam, and the result are all in reasonable limits.
Keywords: rock-fill dam dynamic analysis dam-water-foundation interaction
