摘　　要：穿越人防通道的地下连续墙槽段紧邻DN1 000输配水管线、天津大道主干路,施工场地狭小,为保护邻近管线以及最大限度地避免管线、地面沉降,并且解决施工场地狭小、工期紧迫的难题,采用“封堵+清障”结合的方式对人防通道进行处理。结果表明:成槽过程中泥浆未流失,地下连续墙施工成槽质量合格,管线及地面沉降符合控制值。复杂环境条件下,地下连续墙穿越人防通道处理施工技术的成功应用为类似工程提供了参考。The slot section of underground diaphragm wall passing through civil air defense passage is close to the DN1000 water transmission and distribution pipeline and the main road of Tianjin Avenue,and the construction site is narrow.To protect the adjacent pipelines,avoid pipeline and ground settlement to the maximum extent,and solve the problems of narrow construction site and urgent construction period,the civil air defense passage is treated by the combination of"sealing+clearing".The results show that the slurry is not lost in the process of slotting,the quality of slot section of underground diaphragm wall construction is qualified,and the pipeline and ground settlement meet the control value.Under complex environment conditions,the successful application of underground diaphragm wall passing through civil air defense passage provides a reference for similar projects.
