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 make up for the shortcomings of earthquakes lacking in large earthquakes recorded in the code for seismic design of nuclear power plants (GB50267-97), strong earthquakes, large earthquakes and extraordinarily large earthquakes are selected as supplement to the standard spectrum of GB50267-97, meanwhile, With reference to RG1.60 and RG1.60, the method of making no distinction between hard ground and bedrock ground is adopted. The probability and statistics method is used to integrate the spectrum values ​​of hard ground and bedrock ground. Suggested value for amplitude correction.
