摘　　要：结合上海地区某条地铁线路定期沉降监测的实践,论述了地铁盾构隧道与高架桥梁沉降监测方案的设计与实施;介绍了地铁沉降测量精度控制措施;研究分析了全线沉降变形特点及规律;总结归纳了软土地区地铁结构易出现异常沉降变形的情形,可为软土地区地铁沉降监测的实施及变形分析提供参考。This paper discusses the design and implementation of settlement monitoring schemes for subway shield tunnels and elevated bridges,drawing upon the practice of regular settlement monitoring conducted on a subway line in Shanghai.It proposes measures to control the accuracy of subway settlement measurements.Additionally,it analyzes the characteristics and patterns of settlement deformation across the entire line and summarizes situations prone to abnormal settlement deformation of subway structures in soft soil areas.The above research provides a reference for the implementation of subway settlement monitoring and deformation analysis in soft soil areas.
