【摘要】 河北省目前主要采用的是霍俊荣给出的适用于中国华北地区的地震动反应谱的衰减,该衰减关系分为Ⅱ型衰减关系模型和Ⅲ型衰减关系模型。使用Ⅱ型、Ⅲ型模型以及烈度衰减关系,对石家庄、邯郸、邢台、保定、张家口、承德、唐山、秦皇岛、廊坊、沧州10个地级市以及沙城、三河、宁晋、磁县等曾经历史上发生过大地震的地方,进行50年超越概率10%的峰值加速度和烈度值的计算,得出不同衰减关系模型适合使用于不同地区。更多还原

【Abstract】 Mainly used in Hebei province is the attenuation of response spectra for Huo Junrong given in North China land,the attenuation relationship is divided into type II attenuation model and type III attenuation model.The use of type II,III type model and the intensity attenuation relationship,to Shijiazhuang,Handan,Xingtai,Baoding,Chengde,Tangshan,Zhangjiakou,Qinhuangdao,Langfang,Cangzhou 10 cities and three rivers,Ningjin,Shacheng,Cixian once happened in history earthquake place,calculate the peak of 10% probability of exceedance in 50 years acceleration and intensity value,obtains the different attenuation model suitable for use in different regions.更多还原
