城市地下综合管廊对于城市建设具有重要意义，可以防止管线破裂，杜绝反复开挖路面，有效缓解交通拥堵。在对国内外城市地下综合管廊调研的基础上，通过对国内外城市地下综合管廊建设管理模式的对比分析，总结我国综合管廊建设存在的问题，提出通过PPP模式投资建设综合管廊并建立公司化运作、物业化管理的运营管理模式的建议。同时根据新、老城区的特点，在规划、设计和施工等方面提出相应的建议，重点分析城市地下综合管廊在管线收容、埋深、横断面、交叉节点、抗震等方面的设计问题，并对城市地下综合管廊与其他城市地下空间一体化设计进行分析，从规划、设计、施工等方面为城市地下综合管廊的建设和推广提供参考。

The underground utility tunnel is very important to urban construction in terms of pipeline, road and traffic protection. The stateoftheart of the urban underground utility tunnels in China and abroad is studied; comparison between construction management models of underground utility tunnels in China and abroad is made. The key issues of construction of underground utility tunnels in China are summarized. And then a construction management model of underground utility tunnel by using PPP mode is proposed. Suggestions are given in terms of planning, design and construction based on the characteristics of newlybuilt district and old district. The designs of pipeline storage, cover depth, crosssection, connection points and seismic resistance are analyzed emphatically. The integration between underground utility tunnel and underground space is analyzed. The results can provide reference for construction and popularization of underground utility tunnels.
