摘　　要：在收集了世界范围内自由场地的近断层地震记录基础上,综合考虑台站场地和震级的差别,应用统计分析方法对近断层地震动的峰值加速度的衰减关系进行了研究,并与实际记录进行了比较,发现场地和震级的共同作用对近断层地震动的影响是显著的,为进一步的研究提供了参考.The attenuation relationships are presented for peak ground acceleration based on site and earthquake magnitude by collecting and analyzing the worldwide free- field near- fault records, which are compared with the collected near- fault ground motions. We could draw a conclusion that the influence of combined site and earthquake magnitude on near- fault ground motions is remarkable, which can be applied to the following research of near- fault ground motions.
