摘要: 以上海轨交14号线大世界站上跨西藏南路电力隧道工程为背景,对在建地铁车站对既有电力隧道的影响及相
应的施工保护措施进行了研究。通过分析在建车站对电力隧道变形的控制难点,采取了土体加固、基坑分块实施及增
设抗拔桩等相应的保护措施,并通过三维有限元分析了地铁动荷载对隧道沉降变形的影响,获得了相应的数值分析结
果,经与同类型既有地铁车站的变形监测数据进行对比,证实数值分析结果与实测数据变形趋势一致,可为今后相似
工程提供参考。

Abstract: Based on the background of electric power tunnel project across South Xizang Road over Shanghai Metro Line
14 Dashijie Station, the influence of the subway station under construction on the existing electric power tunnel and the
corresponding construction protection measures are studied. Through the analysis of the difficulties in the deformation
control of electric power tunnel affected by the station under construction, the corresponding protection measures are
taken, such as soil reinforcement, sectioned construction of foundation pit and addition of uplift piles. The influence of
subway dynamic load on tunnel settlement is analyzed by 3D finite element method, and the corresponding numerical
analysis results are obtained. Compared with the deformation monitoring data of the same type of existing subway
stations, it is confirmed that the deformation trend of the numerical analysis results is consistent with the measured data.
It can provide reference for similar projects in the future.
