核电厂抗震设计规范标准谱的修正建议值

Suggested Corrections of Standard Response Spectrum in Code for Seismic Design of Nuclear Power Plants

为了弥补我国《核电厂抗震设计规范》(GB50267-97)制定时参考的地震动缺少大震记录的缺陷,选取强震、大地震和特大地震记录作为GB50267-97制定标准谱时的补充,同时参考RG1.60和修正RG1.60不区分硬土场地和基岩场地的做法,用概率统计的方法,将硬土场地和基岩场地的谱值进行整合,给出了GB中高频段反应谱幅值的修正建议值。

In order to compensate for a lack of strong earthquake records when Code for Seismic Design of the Nuclear Power Plant （GB50267-97） was drafted at that time, the records of strong earthquakes and great earthquakes are chosen as a supplementary for revising the standard response spectrum in GB50267-97. Referring to the way of not distinguishing between the hard field and rock field in RG1.60 and modified RG1.60, the response spectrum of hard field and rock field are integrated, and the suggested corrections of response spectrum are obtained at intermediate frequency and high frequency in GB with the method of probability statistics.
