摘　　要：以上海轨道交通18号线复旦大学站车站深基坑为依托,结合现场变形监测结果,分析了围护结构施工、基坑开挖过程以及结构回筑前后邻近箱涵的沉降变形。通过对邻近污水箱涵及建筑物采取打设隔离桩、跟踪注浆、地下水回灌等多种预防保护措施,有效控制其沉降、变形,为后续类似工程起到了良好的工程示范作用。Based on the deep foundation pit of Fudan University Station of Shanghai rail transit line 18,combined with the field deformation monitoring results,the construction of support structure,the process of foundation pit excavation and the settlement deformation of adjacent box culvert before and after structure reconstruction are analyzed.The settlement and deformation of adjacent sewage box culverts and buildings are effectively controlled by taking various preventive and protective measures such as driving isolation piles,tracking grouting and groundwater recharge,which has played a good engineering demonstration role for subsequent similar projects.
