摘　　要：2023年8月23日辽宁省普兰店区发生M4.6地震,辽宁省强震动台网共获取了34组强震记录,其中震中距为11.7km的普兰店台获取的EW分向最大加速度峰值为280.1cm/s²,是我省强震动台网迄今为止记录到的最大的加速度记录。本文针对强震动台站的记录峰值、频谱、PGA分布规律、V/H比值等进行了分析。On August 23,2023,M4.6 earthquake occurred in Pulandian,Liaoning Province.34 sets of strong earthquake records were obtained by the Liaoning Province Strong Seismic Network.The seismic epi-center was 11.7km.And the maximum acceleration peak of EW direction obtained was 280.1cm/s²,which is the largest acceleration record recorded by Liaoning Province Strong Seismic Network so far.In this paper,the recorded peak value,spectrum,PGA distribution and V/H ratio of strong vibration stations are analyzed.
