城市地铁地表沉降风险防控中微动探测技术的应用研究

Research on the Application of Micro Motion Detection Technology in the Prevention and Control of Ground Subsidence Risk of Urban Subway

微动探测技术可为城市地下空间提供精细化勘探。论文依托某市地铁2号线隧洞工程,从微动探测技术的概念出发,指出了城市地铁地表沉降风险防控中微动探测技术的应用要点,阐述了通过数据采集、探测覆盖层厚度和基岩层形态等方法。

The micro motion detection technology can provide fine exploration for urban underground space. Based on the tunnel project of subway Line 2 in a city and the concept of micro motion detection technology, this paper points out the key points of application of fretting detection technology in the prevention and control of surface subsidence risk of urban metro, and expounds the methods of data acquisition, detection of overlying layer thickness and bedrock layer morphology.
