| 摘 要： | 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△=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

| Abstract: | Based on the data collection of earthquake monitoring stations and networks in Sichuan province, 27 bedrock stations from May 12 to June 10 in 2008 acquired 8505 broadband velocity records from 105 earthquakes (magni-tude ML=4.0-6.4, epicentral distance △=26-623 km), using real-time sim-ulation methods we obtained corresponding acceleration records. Then by a re-gression analysis of data the peak ground acceleration and velocity attenuation relation for small and moderate bedrock Sichuan earthquakes were obtained. The relation is verified by a recent 4.8 earthquake in Wenchuan. This paper presents the attenuation relations for Sichuan region by using Sichuan Seismic Network records. |
