某核电站循环水泵房结构的地震反应分析
|
摘要
文中运用动力时程反应分析方法,针对某百万千瓦级核电厂,利用Ansys对循环水泵房结构进行了抗震分析。针对循环水泵房结构场地岩性、结构特点,分别考虑不同设计水位、运行和检修情况、波浪压力、静动水压力和土压力以及地震荷载的组合工况,对结构进行了抗震性能计算分析,得到结构构件各个截面上内力包络,该成果对循环水泵房结构设计具有参考价值和指导意义。
Using dynamic time-history response analysis method,seismic analysis of circulation water pump house in the million-kilowatt nuclear power plant is carried out in this paper.Based on rock properties and structural characteristics of circulating water pump house,all kinds of combination with different design water levels,operation and maintenance conditions,wave pressure,static and dynamic water pressure and soil pressure and seismic loadings are considered.The internal force envelope of each section of the structure is obtained and the results can provide reference value and guidance significance for the structural design of circulating water pump house.
