摘要
针对某强震区分离式泵站的初步设计方案,基于ADINA有限元程序,建立了结构-地基-水体三维有限元动力分析模型,分析了分离式泵站的动力特性。运用流固耦合分析方法和时程分析方法,研究泵站在0.3 g地震作用下的动力响应,给出了泵站抗震的薄弱位置,研究成果可为工程设计提供参考。
Based on preliminary design of a separated pumping station in meizoseismal area,a 3D dynamic finite element analysis model of structure-foundation-water was developed to analyze the dynamic characteristic of the separated pumping station.Fluid-solid coupling method and time history analysis method was used to calculate the dynamic response of the pumping station with peak acceleration of 0.3g.The week location of the pumping station for earthquake occurrence is given.The results will provide reference for the engineering design.
