摘　　要：北京高丽营镇是北京地区地裂缝灾害高发的区域之一,“十五”以来,北京市地震局在高丽营地区地裂缝活动区开展了大量的工作,并根据期间地表破裂现象的现场调查得出了地裂缝北东向活动的认识。本文对北京顺义高丽营地区不同时期单孔法、瞬态多道瑞雷波法及折射走时层析成像数据进行了处理,分别提取测井及折射走时层析成像(Tomography)中的剪切波(S波)速,并通过转换得到瞬态多道瑞雷波法(MASW)的剪切波速后,对剪切波速度特征进行分析。分析结果印证了该地区2004年至2017年间地裂缝北向活动的认识。Gaoliying is one of the regions in Beijing with high risks of ground rupture disasters. During the Tenth-Five-Year Regulation, the Beijing Earthquake Administration has developed a lot of re-search in Gaoliying ground rupture activity region and has characterized the North-East trend activity based on the ground rupture field work. This article processed the drilling data, the multichannel analysis of surface waves (MASW) method, the refraction tomography data in different collection time, and obtained the S-wave velocities from different methods. By analyzing the S-wave velocity features, the north-trend activity of the Gaoliying ground ruptures from 2004 to 2017 was inferred.
