【摘要】 肯斯瓦特面板砂砾石坝全断面由砂砾石填筑,工程区处于强震区,大坝设防烈度Ⅸ度,设计取消了过渡料区。根据肯斯瓦特大坝的分区设计,在坝料静、动力特性试验和三维静力分析的基础上,采用三维真非线性有效应力地震反应分析及安全评价方法,对大坝进行了给定地震情况下的地震反应分析和评价。从大坝的动力计算分析结果看,该坝能够满足给定地震工况下的抗震安全性要求。更多还原

【Abstract】 The Kenswat Dam locates in meizoseismal area and the fortification intensity is IX degree.The dam is entirely filled with sand and gravel and not sets transition material zone in design.According to the zoning design of Dam,the static and dynamic characteristics test and three-dimensional static analysis of dam material are made and the seismic response analysis and safety evaluation of dam are simulated by a 3-D authentic nonlinear method under given earthquake magnitude.The results show that the dam can meet the requirements on seismic safety.更多还原
