摘　　要：以某市区地铁三号线下穿地铁四号线区域为例,介绍了自动化实时监测技术的应用要点,并对监测数据进行整理分析,进一步总结出本项目施工活动对地铁隧道结构的影响规律。结果表明:在地铁三号线穿越过程中,沉降值最大点为监测点R4-7,累计变形值达-11.2 mm;根据监测结果将地铁结构沉降大致分成3个不同时期,其中沉降变化较大的是第二个时期;分析总结盾构施工对地铁结构变形的影响,为相关工程提供指导和参考。Taking the area where Metro Line 3 passes under Metro Line 4 of an urban area as an example,this paper introduces the application of automatic real-time monitoring technology,analyzes the monitoring data and further summarizes the impact of the construction activities of the project on the subway tunnel structure.The result shows that during the crossing of Metro Line 3,the maximum subsidence value is R4-7,and the accumulated deformation value is-11.2 mm;According to the monitoring results,the subsidence of the subway structure can be roughly divided into three different periods,of which the second period is the one with large subsidence change;The influence of shield construction on subway structure deformation is analyzed and summarized,which provides guidance and reference for related projects.
