摘要

地震发生后,一般都是用烈度衰减关系来初步评估烈度分布。为了研究该方法的偏差特性,首先利用138次地震事件回归出我国大陆地区的烈度衰减关系,然后应用该衰减关系,以我国大陆地区1966年以来震级在6.0级以上的43次地震事件的评估结果,总结出应用烈度衰减关系评估烈度分布时的偏差特性,并提出了相应的改进建议。
After an earthquake,seismic intensity attenuation law is always used to estimate the intensity distribution.In order to find the deviation of this method,seismic intensity attenuation for mainland of China was fitted by using 138 earthquake events in this region.With the application of this attenuation,43 earthquakes(M≥6.0) intensity distribution were evaluated.Based on the results,some conclusions and suggestions for improvements of evaluation are proposed.
