摘要
对收集到的近两万条美国西部的强震记录进行了分析整理,选用了108个台站共324条基岩强地震动记录,对建议的地震动参数衰减模型进行了统计。该地震动参数衰减模型小考虑了区域介质品质因子,试图通过不同地区介质品质因子的差异规律来实现地震动参数衰减特性的相互转换,这对缺乏强震记录资料地区的地震动参数估计将带来极大的方便。
Strong ground motion records have been analyzed by collecting twenty-thousands records of west American 324 bed rock motion records in 108 stations were selected to regress the proposed attenuation model for parameters of ground motion. In order to reflect the effect of regional quality on earthquake ground motion attenuation law, two types of earthquake ground motion attenuation formulas have been utilized in the study, one includes regional quality factor and other is often used in the engineering earthquake. The statistical regression for the parameters of the model are achieved by the least square method. The relationship of two models were compared with regressive relation by other authors.
