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。本文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粘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。
Abstract
The pump building of CPR1000 nuclear power plants as seismic category I structure, the calculation of earthquake action and the sliding stability analysis under the ultimate safety ground motion(SL-2) is the very important part for the pump building structural design and the stability analysis. Comparative analysis of earthquake action and the sliding stability analysis is carried out based on the lumped parameter models recommended by seismic design codes of ASCE4-98 and viscous-spring artificial boundary model and massless foundation model. Finally, the rule of the earthquake action and the sliding stability analysis with different sites and the different dynamic numerical site models for this certain lumped mass model of pump building is summed up.
