基于四川省地震监测台网27个基岩台站,2008年5月12日—2008年6月10日105次地震(震级ML=4.0—6.4,震中距Δ=26—623km)的8505条宽频带速度记录,利用实时仿真方法得到了相应的加速度记录,进而对数据进行回归分析,获得了四川地区基岩场地中小地震峰值加速度和峰值速度的衰减关系,并用最近发生的一次4.8级地震对该规律进行了验证.通过四川台网的记录,提出了符合四川地质条件的衰减关系.
Based on the 850 bedrock stations of 27 bedrock stations of the Sichuan Earthquake Monitoring Network, 105 earthquakes (magnitude ML = 4.0-6.4, epicentral distance Δ = 26-623km) from May 12, 2008 to June 10, 2008, With the velocity record, the corresponding acceleration records were obtained by using the real-time simulation method, and then the data were regressed and analyzed. The attenuation relation between the peak acceleration and the peak velocity of the medium and small earthquakes in the bedrock site of Sichuan Province was obtained. Based on the recent 4.8 earthquakes, The law was verified.Through the record of Sichuan Taiwan Network, the paper proposed the attenuation relationship which accords with the geological conditions in Sichuan.
