Abstract: The field characteristics and regional features in the data of ground motion, the consistence of definiticns of variables and the distribution extent of the original data must be considered in the fitting the record ground motion data to the acceleration attenuation relation. Generally, the digital method should be used to get the acceleration attenuation relation through data transform, but the analysis method may be used only under the special condition. The special seismic attenuation characteristics should be considered when the seismic intensity anomaly and very large earthquake are presented.

Key words: Nuclear power plant siting, Seismological ivestigation, Seismic intensity attenuation, Acceleration attenuation relation

摘要: 在由地震动加速度资料拟合加速度衰减关系时应注意资料的场地特征及区域代表性、变量定义的一致及原始数据的分布范围等。利用参考地区的烈度及加速度衰减关系和工作地区的烈度衰减关系用转换方法求工作地区的加速度衰减关系时,只有在特定情况下才能用解析方法转换,一般宜采用数值方法。建议在核电厂选址工作中,对存在烈度异常等情况及有特大历史地震时要考虑特定地震的衰减特征。
