摘要
CPR1000核电机组的联合泵房作为抗震Ⅰ类物项,在极限安全地震动(SL-2)作用下厂房结构地震作用及基础抗滑稳定性分析是结构设计的重要环节。以某联合泵房的集中质量简化模型作为研究对象,基于ASCE4-98规范推荐的集总参数地基模型、无质量地基模型以及黏弹性人工边界场地模型,开展了泵房结构的地震作用以及基础的抗滑稳定性对比分析,并总结了其随不同类型的均质和分层场地以及不同的场地动力数值模型的变化规律。
Regarding the pump building of CPR1000 nuclear power plant （NPP） as a seismic category I structure, the calculation of earthquake action and the analysis of sliding stability under ultimate safety ground motion （ SL- 2） are very important parts in the pump building structural design. A comparative analysis on the earthquake action and sliding stability was carried out based on the lumped parameter models recommended by the seismic design code of ASCE4-98 as well as the models of viscous-spring artificial boundary and massless foundation. The results of the earthquake action calculation and the sliding stability analysis at different sites and with different numerical dynamic models of sites for a certain lumped mass model of pump building were summed up.
