摘要

我国大量位于高烈度地震区的水电工程正在规划、建设中,强震发生时,地面厂房损毁和人员伤亡情况触目惊心,高地震烈度区河岸式厂房的抗震设计是必须重视的问题。对位于9度抗震设防区的小清河七级水电站厂房进行了详细的三维有限元分析,分别对结构调整、设防烈度地震、多遇地震、罕遇地震等工况进行了分析和验算,其分析过程和研究成果对此类工程的研究和设计有很好的参考价值。
Many hydropower stations are planned and being constructed in high seismic intensity zones in China.When the great earthquake strikes,lots of ground factory buildings are ruined and thousands of people are killed,which is awfully shocked.The seismic design of hydropower plant building located in high seismic intensity zone is focused on by engineers.In this paper,the Xiaoqinghe hydropower station bank plant house which will be constructed in grade 9 seismic fortification intensity zone is analyzed with the 3-dimensional Finite Element Method.The building’s structure is analyzed and checked in 4 load cases of structure adjustment and different seismic intensity earthquakes.The analysis procedure and conclusions of this paper offers a valuable reference to the same kind of projects.
