【摘要】 由于我国地区差异性很大,存在着不同的烈度衰减关系。本文根据鞍山市区域地震地质资料,采用我国东北部烈度衰减关系模型与国家标准第四代区划图,以地表峰值加速度来代替地震烈度,然后以Arc GIS为平台,二次开发对鞍山市的设定地震影响场进行分析研究。更多还原

【Abstract】 Because of great area imparity of china,different intensity attenuation exists.In the paper,according to regional seismic-geologic material of anshan city,adopting to intensity attenuation modal of northeast china and the forth generation standard block plan,it makes ground peak acceleration replace seismic intensity.And then,it uses Arc GIS software as re-exploiting platform,and analyzes scenario earthquake affection of anshan city.更多还原
