【摘要】 基于南水北调东线工程皂河泵站软基上建站特点,建立了结构~桩~地基的三维有限元动力分析模型,研究了软基上半埋式泵站动力分析方法,分析了泵站结构的动力特性和8度地震下结构的动力响应。研究成果为工程设计与施工提供了科学依据,并为同类结构的抗震设计提供了有益的参考。更多还原

【Abstract】 Base on the characteristics of the construction of Zaohe Pumping Station,which is a semi-buried one on soft-foundation,of the East Route of South-to-North Water Transfer Project,a 3-D finite element model for the dynamic analysis on the seismic responses from the system of superstructure-pile-foundation is established;with which the method for the dynamic analysis on pumping station is studied,and then the dynamic characteristics and dynamic responses of the structure under the seismic intensity of 8-degree are analyzed.The study has provided a scientific basis for the design and construction of the project and can give a better reference for the seismic design of the similar structures as well.更多还原
