摘要

分析AP1000设计地震反应谱(CSDRS)与各相关导则中定义的反应谱的对应关系,指出在特定厂址评价中,应基于同一标高比较厂址特定设计反应谱(SRS)和AP1000CSDRS。基于5种设计场地模型将AP1000CSDRS反演至设计基岩处和核岛结构基础底部,计算得到设计基岩处和结构基础底部的AP1000设计谱。计算结果表明,AP1000CSDRS不能包络已有核电厂核岛结构抗震设计采用的0.2g标定的RG1.60的设计反应谱;若在非硬质基岩场地建造AP1000核岛结构,应进行AP1000CSDRS的保守性分析。
The relation between AP1000 certified seismic design response spectra(CSDRS) and the response spectra defined by different regulations were analyzed,and it indicated that it was necessary to compare the site specific response spectra(SRS) with AP1000 CSDRS on the same ground level.The corresponding CSDRS at two levels of design rock and foundation base were calculated by inversion method for the five AP1000 design site models.The analysis results show that the calculated CSDRS at two levels of design rock and foundation base could not envelop the design response spectra anchored at the peak ground acceleration of 0.2g,which is used in the seismic design of nuclear island of existing nuclear power plant as specified in RG1.60.Therefore,it is suggested that if the AP1000 nuclear power plant is not built on the hard rock site,the conservative analysis of the AP1000 CSDRS should be carried out.
