| 摘 要： | 基于流固耦合分析方法,分别应用势流模式和位移模式2种流体单元模拟库水,并与传统的附加质量方法模拟库水的方法做了比较,结果显示该方法可行;相比附加质量方法,流固耦合方法与理论解更为接近,其中位移模式流体单元对单元形态要求较高.对库水截取区域的敏感性分析表明,流体区域选取3～5倍坝高可以得到较为满意的结果.以重力坝的不同坝...

| Abstract: | Dam-reservoir interaction was analyzed in this paper using fluid-solid coupling method.The reservoir water was modeled respectively by two types of finite element,namely pressure-based element and displacement-based element.The fluid-solid coupling method was compared with traditional Westergaard additional mass method and the comparison showed that the former was closer to the theoretical solution than the latter.The displacement-based element demanded more regular element shape than pressure-based element... |
