简介:本文对国家强震动台网中心收集的2008年5月12日14时28分04秒汶川8.0级地震中获取的420组三分量加速度记录进行了处理和初步分析。在这次地震中布设在龙门山断裂带及其周围地区的50多个台站获得了大于100gal的加速度记录,有46组三分量加速度记录的断层距小于100km,使中国大陆近断层区域所获得的强震动加速度记录的数量成倍增加。本文依据这批数据,对汶川大地震强震动特性进行了初步分析,给出了此次地震断层附近地区的PGA衰减规律,并利用此规律模拟了断层附近的加速度峰值,绘制了PGA分布图、竖向PGA与水平向PGA比值图;给出了汶川地震断层附近的加速度反应谱、上盘效应、竖向效应、速度大脉冲效应等地震动特征,这些特征可作为抗震设计规范修订的依据并供灾区重建时参考。
