摘　　要：顶管等非开挖工艺遭遇地下不良土层或障碍物后的快速处理工艺,越来越受到重视。退管法是解决顶管遭遇地下不良土层或障碍物后行之有效的工艺之一,具有投资少、工期短、不额外占用地下或地面空间等诸多优点,可为后续管道施工提供灵活的管位位置。总结的经验可供今后类似工程借鉴。Trenchless processes such as pipe-jacking are receiving more and more attention as a rapid treatment process after encountering undesirable subsurface soils or obstructions.Receding pipe method is one of the effective techniques to solve the problem of pipe-jacking after encountering underground bad soil or obstacle,which has many advantages such as less investment,shorter construction period,not taking up extra underground or ground space,etc.,and can provide flexible pipe location for subsequent pipeline construction.The summarized experience can be used as a reference for similar projects in the future.
