摘　　要：城市地下综合管廊的出线节点是综合管廊的重要组成部分,也是管廊设计中的难点和管廊施工的重点。不同出线节点的管廊结构埋深不一,结构受力不同,施工顺序不同等。以六盘水综合管廊工程(下出线)和贵阳白云管廊工程(上出线)为例,从工艺、结构、施工、成本4方面对上出线节点和下出线节点进行简要对比。The outlet joint of the urban underground comprehensive utility tunnel is an important part, and is also a difficult point and key point in the design of the utility tunnel construction. The utility tunnel structure with different outlet connections has different buried depth, different structure force and different construction order and so on. Taking Liupanshui comprehensive utility tunnel （lower outlet line） and Guiyang Baiyun utility tunnel （ upper outlet line） as an example, the upper and lower outlet joints are briefly contrasted from four aspects of process, structure, construction and cost.
