摘　　要：以韩江榕江练江水系连通后续优化工程盾构工作井为例,分析了富水软弱复杂地层超深竖井施工的重难点,对地下连续墙成槽、超深竖井开挖、内衬墙结构施工等关键工序提出针对性施工关键技术措施,提高了盾构工作井施工质量,相关技术可为类似工程施工提供借鉴。Taking the example of the shield tunneling work well in the subsequent optimization project of the Hanjiang Rongjiang Lianjiang water system connection,Analyzes the key and difficult points of excavation construction for ultra deep vertical shafts in complex and weak strata with rich water.Targeted construction key technical measures are proposed for key processes such as underground continuous wall slotting,ultra deep vertical shaft excavation,and lining wall structure construction,which improves the construction quality of shield tunneling wells.Relevant technologies can provide reference for similar engineering construction.
