【摘要】 针对睢宁二站分离式泵站特点,采用非线性有限元ADINA软件,建立了睢宁泵站的结构地基水体三维有限元动力分析模型,分析比较了正常抽水状态下两个设计方案泵房结构的动力特性,运用流固耦合及时程分析方法分析了泵房结构在8度(0.3g)地震时的动力响应,给出了推荐方案。研究结果可为工程设计施工提供参考依据。更多还原

【Abstract】 Based on the property of separating Suining Pumping Station Ⅱ,three dimensional dynamic finite element analysis model of structure foundation water body is built by ADINA to compare and analyze the dynamic characteristics of pump house structure on two design schemes under the normal pumping condition.Fluid solid coupling and time-histories analysis methods are used to calculate the dynamic response of the pump house structure with acceleration of 0.3g.The results provide scientific reference for engineering design and construction.更多还原
