邳州水电站泵房结构三维地震动力响应分析
|
摘要
邳州水电站是南水北调东线工程的第六级泵站,泵房为1级水工建筑物。邳州水电站地下部分为大体积混凝土结构,采用堤身式布置,整体块基型结构;地上部分采用框架柱,柱间砌筑砖墙围护。邳州水电站在南水北调整体项目中战略意义重大,基础设施造价颇高,本研究分析了本工程在地震下的安全性能、泵站下部结构和上部结构的内力和变形情况,对泵站的结构型式及布置等进行了分析和评价,达到了指导泵房设计施工的优化和调整的目的。
Pizhou Hydropower Station is the sixth grade pumping station of south-to-north water diversion project,and the pumping station is a hydraulic structure of Grade 1.The underground part of Pizhou Hydropower Station is a large-volume concrete structure,which adopts the levee-type arrangement and the overall block-based structure;the aboveground part uses the framework columns and masonry walls between columns envelope.Pizhou Hydropower Station is of significance in south-to-north water diversion project and the infrastructure cost is high.This paper analyzed the safety of the structure under earthquake,the internal forces and deformations of the underground and aboveground parts of the station.Also the form and layout of the structure are analyzed and evaluated,which are used in the optimization and adjustment of the design and construction of the station.
