Abstract: There exists a ground rupture zone along north section of the Shunyi Liangxiang fault zone near Beijing. We have made field investigation, chemical exploration and trough exploration to study its cause. It is suggested that this rupture zone reflects recent activity of north section of the Shunyi-Liangxiang fault. Seismicity along this fault section as well as potential hazards caused by it should be taken into consideration for construction planning.

Key words: Shunyi ground rupture zone, Shunyi Liangxiang fault, Engineering safety

摘要： 沿北京顺义-良乡断裂北段存在地表破裂带。对这条破裂带进行了成因分析、野外调查、化探和槽探研究,认为该破裂带反映了顺义-良乡断裂北段的现今活动性。今后应注意沿该段断裂的地震活动并在建设规划中充分考虑它对工程可能造成的灾害。
