摘　　要：随着城市化进程的加速,地铁盾构施工作为一种高效、安全的隧道开挖方式,广泛应用于城市轨道交通建设中。在穿越复杂地质和敏感区域的施工中,地面沉降造成的建筑物、基础设施损害已成为主要风险。因此,以厦门市轨道交通3号线南延段为背景,对项目的主要风险进行归纳,提出地上、地下协同监测技术和沉降控制措施。通过协同分析隧道施工过程中的多源监测数据,结合地表沉降、建筑物位移及隧道壁后注浆质量等数据,确保隧道安全穿越关键区域,并以穿越厦大海滨大楼为例进行详细分析和具体应用,可为同类工程的施工提供参考。With the acceleration of urbanization,metro shield construction is widely applied in urban rail transit projects as an efficient and safe tunnel excavation method.In projects involving crossing of complex geological and sensitive areas,damage to buildings and infrastructure caused by land subsidence constitutes a primary risk.Based on the south extension of Xiamen Rail Transit Line 3,main project risks are summarized and ground and underground coordinated monitoring technique and settlement control measures are proposed.Multi-source monitoring data during tunnel construction—including surface subsidence,building displacement,and grouting quality behind tunnel walls—are analyzed in a coordinated manner to ensure safe tunnel passage through key areas.Taking Xiamen University Haibin Building as an example,detailed analysis and practical application are conducted,providing reference for similar projects.
