摘    要:本文以秦皇岛市青龙县城工程场地为例,采用A·Der·Kiureghian和A·H-SAng断层-破裂模型,通过潜在震源识别及震源区划分、地震动参数确定、地震动衰减公式计算模型建立及不确定性校正、场地地震危险性评定等思路和方法,对该场地进行了地震危险性分析和评定。结果认为,该场地建筑物按50年使用期,地震烈度为6.72度,其地面峰值加速度为0.103g;一般建筑物按Ⅵ度烈度设防,重要建筑则按Ⅶ度烈度设防;可能产生的Ⅷ度烈度主要来自西南方向的唐山地震区。

关 键 词:地震危险性分析;断层-破裂模型;青龙县城工程场地

Abstract:Taking the engineering sites in Qinglong county, Qinhuahgdao c.ity for an example and adopting A DerKiureghian and A. H-A. Aug's fault-rupture model, this paper engages in seismic risk analySis and evaluation for the sites. Through the basic ideological method it takes the following concrete analytical steps:1. ftscetning the potential earthquake source and dividing the seismic source areas I2. Determining the seismic active parameters I3. Fixing the seismic shock--attenuation formula, the faultrepture lenghth and the earthquake scale relation formula I4. Setting the calculation model and cerreecting the undetermined abilityt5. Evaluating the seismic risk analysis of the sites.
Keywords:Seismic risk analysis   fault-rupture model   engineering site of Qingtong county
