摘　　要：某因使用需求,设计连通口位置的地铁外墙并未预留接口,施工凿除既有地铁墙体时可能会造成结构较大变形,影响结构安全,因地铁预留接口与项目设计的连通口无法适配,造成连通口开洞需在原有地铁外墙上进行施工,地铁外墙开口处因无暗梁及暗柱,导致施工过程中易造成原有结构的变形,影响地铁的运行。针对此种情况,首先介绍工程概况,阐述地铁开口设计的内容,并在此基础上,对地铁施工工艺、防水作法进行分析,为今后工程技术人员研究地铁既有结构洞口开设施工技术提供经验借鉴。Due to the use requirements,no interface is reserved for the exterior wall of the subway designed for the location of the connecting port,which may cause large structural deformation and affect the structural safety when the existing subway wall is cut out.As the reserved interface of the subway cannot be adapted to the connecting port designed by the project,the opening of the connecting port needs to be constructed on the exterior wall of the original subway.It is easy to cause the deformation of the original structure in the construction process and affect the operation of the subway.Therefore,this study first introduces the general situation of the project,expounds the content of the subway opening design,and on this basis,analyzes the subway construction technology and waterproof practice,which provides experience for future engineers and technicians to study the construction technology of the existing structure opening of the subway.
