摘　　要：同隧道工程一样,防水工程是城市综合管廊建设质量控制的关键环节。通过介绍防水设计原则、防水等级选择,并以上海市松江区某综合管廊工程为例进行研究,总结软土地区综合管廊防水工程的实施要点,如主体结构自防水、主体结构外(底板、侧墙和顶板)防水和细部结构(变形缝、施工缝和预埋管)防水,为今后国内类似工程提供借鉴。Like the tunnel engineering,the waterproof engineering is the key link of quality control in the construction of urban utility tunnel.By introducing the selection of waterproof design principle and waterproof grade,and taking a utility tunnel in Songjiang District of Shanghai as an example for the study,the implementing essentials i.e.self-waterproofing of main structure,waterproofing outside of maim structure(baseplate,side wall and roof) and waterproofing of detailed structure(deformation joint,construction joint and embedded pipe) in the utility tunnel waterproof engineering in the soft soil area are summarized,which provides the reference for the similar projects in China in the future.
