基于国内某大型水利工程进水塔结构,采用ADINA大型结构分析软件,利用其势流体单元模拟水体,构建了塔体—地基—水体三维非线性流固耦合有限元分析模型,分析了进水塔塔顶排架结构及塔体自振特性、地震反应,研究了塔顶排架结构对进水塔动力响应的影响,结果可为进水塔结构的抗震设计提供参考。 Based on the structure of inlet tower of a large water project in China, ADINA large-scale structural analysis software was used to simulate the water body with potential fluid elements, and a three-dimensional fluid-solid coupling finite element analysis model of tower-foundation-water body was established. The structure of the top of the tower, the self-vibration characteristics of the tower body and the earthquake response were studied. The influence of the tower structure on the dynamic response of the inlet tower was studied. The results could provide a reference for the seismic design of the inlet tower structure.
