摘要
利用安徽及近邻区地震烈度资料,采用椭圆衰减模型和长轴可转向与近、远场补点方法,通过多元回归方法进行拟合,建立该地区地震烈度衰减关系。该衰减关系用于安徽地震应急指挥技术系统震害快速评估模块,为地震灾害损失快速评估提供基础资料;也可用于安徽地区地震安全性评价、震害预测等防震减灾领域。
Using the seismic intensity data of Anhui Province and its neighbor area,according to the ellipse model,long axis turning and the method of adding control points of the near-far field.We established an intensity attenuation relation of this area. The attenuation relation is used to earthquake damage rapid assessment model of earthquake emergency command system, providing important basic data. The attenuation relation can also be used to seismic safety evaluation and seismic damage prediction in the fields of earthquake prevention and disaster reduction etc.
