摘要
根据重庆及邻近地区地震资料,通过资料处理、衰减模型和统计方法改进,建立了该地区地震烈度衰减关系。结果表明,补点对烈度衰减关系有明显的影响,不同回归法的回归结果相差不大。与已有衰减关系比较,本文结果在中震近场区的拟合效果有明显的改善。
Based on the seismic data of Chongqing and its adjacent areas, the local attenuation relation of earthquake intensity is established through the improvement of data processing, attenuation model and statistical method. It is shown that adding data has a significant influence on the attenuation relation and there is no distinct difference between the regression results of different regression methods. In comparison with previous attenuation relations, fitting effect of this attenuation relation is apparently improved in near-field region of medium shake.
