唐山地区基岩地震动峰值衰减特征研究
|
摘要
基于搜集的唐山地区的强震记录数据,采用考虑地震动峰值加速度、近距离和震级的三种衰减模型,然后利用数理统计回归的方法对这些模型的结果进行了对比和分析,获得了唐山地区基岩场地峰值加速度衰减关系。并用2012年5月28日的唐山4.8级地震对此衰减关系进行了验证。
Based on the collected data of strong motion records in Tangshan region,we apply three attenuation models that considered ground acceleration,close range and magnitude,then use the mathematical statistical regression method to compare and analyze the results of these models,to obtain a new attenuation relationship of peak ground acceleration on bedrock site is established in Tangshan region.The results of our study is good consistent with the observations from the May 28,2012,M4.8 Tangshan earthquake,
