摘要
利用已有的新疆历史地震考察资料,数字化处理后重新量取1716～2010年以来收集到的破坏性地震事件的103幅地震烈度等震线图的烈度外包线,采用多元回归方法拟合,总结新疆地区地震烈度衰减规律。提供了椭圆模型烈度衰减函数,分不同时段和区域进行拟合结果对比,并采用头尾限定的方法给出新疆地区烈度衰减关系。
By using the existing historical earthquake investigation data in Xinjiang, 103 intensity outsoureing lines of destructive earthquakes from 1716 to 2010 were collected after they were digitized. The author summarized the seismic intensity attenuation laws in Xinjiang region through multiple regression fitting. The intensity attenuation function of elliptical model was provided and the fitting result in different periods and areas was compared, finally the intensities attenuation relationship in Xinjiang region was obtained through the head and end limiting method.
