摘　　要：本文针对成熟M310堆型核电厂储液容器辅助给水系统(ASG)水箱,根据ASCE 4—98,采用基于壳模型的有限元法以及两种不同的地震输入,完成了抗震分析,并依据RCC-M规范J篇进行了地震屈曲评价。结果表明,ASG水箱原设计存在一定的地震屈曲风险。在此基础上本文对ASG水箱的结构设计分析给出了建议。The seismic analysis on auxiliary feedwater system （ASG） tank in M310 type nuclear power plant was carried out according to ASCE 4—98 by using finite element method which was based on shell model .The seismic buckling assessment was finished on requirement of subsection J of RCC‐M .T he response acceleration spectra as seismic input were used for analysis .The results show that some risks of seismic buckling on the original design of the ASG tank exist .And some suggestions about structural design analysis were given .
