摘　　要：顶管是管道下穿道路时一种常用的施工工法,可减少对交通的干扰和避免大开挖。顶管工作井的常用施工工法有SMW工法、沉井法等,结合实际案例分析工作井底存在管线情况下采用倒挂井壁法施工工作井的设计要点,以期为类似的工程设计提供借鉴。Pipe jacking is a common construction method when pipelines pass under roads,which can reduce interference with traffic and avoid large excavation.Common construction methods for pipe jacking working wells include SMW method,caisson method,etc.Combined with actual cases,this paper analyzes the design points of the working well construction using the inverted well wall method when there are pipelines at the bottom of the working well,in order to provide reference for similar engineering designs.
