| 摘 要： | 地震震动的衰减关系在地震区划和工程场地的安全性评估过程中是不可或缺的。利用河北及周边区域历史地震的等震线资料,运用统计回归的分析方法,得到统计回归方程及地震烈度衰减关系,与其他烈度衰减关系进行对比分析,并与地震应急指挥技术系统软件及地震烈度分布资料进行对比,从而得到适用于河北及周边地区的地震烈度衰减关系。

| Abstract: | The attenuation relation of earthquake motion is indispensable in the process of seismic zoning and safety evaluation of engineering site. Use of historical earthquakes in Hebei and the surrounding area and isoseismal data, combined with soil coverage area, bedrock outcropped area, with statistical regression analysis method, the statistical regression equation and the seismic intensity attenuation relationship is obtained. The method to obtain the seismic intensity attenuation relationship with other intensity attenuation relationship are compared and analyzed, and compared with the earthquake emergency command system software and seismic intensity distribution data. The seismic intensity attenuation relationship is obtained for Hebei and surrounding areas. |
