摘要
地裂缝土体结构破碎,地下水活动较强烈,围岩稳定性差,给地铁施工造成隐患。通过采用深孔注浆技术结合隧道内拱顶沉降以及隧道净空收敛的监测与其数据分析,确保了地铁隧道的安全施工,说明了该种施工方法和监测技术在地铁施工中的可靠性,并为城市地铁设计施工提供参考。
The structure of ground fissure soil is broken. Groundwater activity is intensity. Rock is poor stability. Subway construction will hazard. Through the deep hole Grouting Technology, top of Tunnel subsidence monitoring and converge of tunnel headroom monitoring, ensure the safety of the subway tunnel construction. The reliability of construction and monitoring in the subway construction was validated. It provides a reference for the design and construction of subway.
