摘要

CPR1000核电机组的联合泵房作为抗震I类物项，其在极限安全地震动(SL-2)作用下厂房结构的地震作用分析是结构设计和基础稳定性计算的重要环节。本文结合土-结构相互作用(SSI)数值分析的最新发展，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、粘弹性人工边界场地模型以及无质量地基模型，开展了泵房结构的地震作用对比分析，并总结了均质场地和分层场地下的地震作用规律，对于泵房的结构设计以及稳定性验算具有一定的指导和参考意义。

Abstract

The pump building of CPR1000 nuclear power plants as seismic category I structure, the calculation of earthquake action under the ultimate safety ground motion(SL-2) is the very important part for the pump building structural design and the stability analysis. With the recent development of soil-structure interaction(SSI) analysis, comparative analysis of earthquake action is carried out based on the lumped parameter models recommended by seismic design codes of ASCE4-98 which is applicable to the homogeneous site and massless foundation model and viscous-spring artificial boundary model which are especially fit for the non-homogeneous site. Finally, the rule of the earthquake action with different sites and the different dynamic numerical site models for this certain lumped mass model of pump building is summed up. This paper provides some reference and guidance significance in the aspect of the structural design and the stability analysis.
