摘　　要：2016年3月21日11时29分甘肃省酒泉市金塔县发生M_S 4.7地震,甘肃省强震动台网中心收集到5组三分向加速度记录,常规处理后得到15条零基线校正后的三分向峰值加速度(PGA),选取土层台基类型的62XID台站加速度记录(PGA数值最大)进行分析,绘制校正后的加速度、速度和位移时程曲线及加速度反应谱,为中国西部工程震害调查提供参考资料。There is an MS4.7earthquake occurred in Jinta County on March21,201611:29.The main shock records of this earthquake obtained by5strong motion stations of Gansu Strong Motion Network.After routine processing,15zero-baseline corrected three points peak accelerations were obtained.The acceleration records(PGA value)of station62XID,which is type of soil base,were selected and analyzed.And the corrected acceleration,velocity and displacement time history curves as well as acceleration response spectra were plotted.This study provides an important reference for seismic damage investigation in western China.

关 键 词：金塔县MS4.7地震 强震动记录 峰值加速度 加速度反应谱
