摘　　要：随着城市轨道交通网络的完善和城市地下空间的持续开发,基坑工程对运营地铁盾构隧道的变形影响问题一直较为突出。针对沉降和收敛这2种地铁盾构隧道变形的主要形式,以上海软土地区某深基坑工程的实测数据为基础,分析了深基坑工程实施各阶段相邻地铁盾构隧道变形发展的特点,探讨了隧道沉降和收敛变形产生的机理,可为基坑施工对相邻地铁盾构隧道变形影响的控制提供参考。With the development of urban rail transit networks and the continuous utilization of underground urban spaces,the impact of deep foundation pit engineering on the deformation of operational subway shield tunnels has become a significant issue.Focusing on settlement and convergence as the primary forms of shield tunnel deformation,deformation characteristics of adjacent subway shield tunnels during different stages of a deep foundation pit engineering project in the soft soil region of Shanghai are analyzed based on measured data.The mechanisms behind tunnel settlement and convergence deformation are investigated,providing a reference for controlling the impact of excavation on the deformation of adjacent subway shield tunnels.
