摘　　要：在天津滨海新区中央大道工程新港四号路地道综合管沟的设计中,尝试以大直径(DN3000)预应力钢筒混凝土管道(PCCP)作为综合管沟的管材,同时依托中央大道地道修建,利用津滨轻轨托换的工艺箱体对管沟进行连接。介绍了管沟断面形式、管线布置、基础做法、防水措施、接口处理、节点处理及配套设施等设计内容,为综合管沟的建设积累了经验。In the design of utility tunnel under Xingang No 4 Road underpass in the Central Avenue project in Binhai New District of Tianjin, using prestressed concrete cylinder pipe （PCCP） with 3 000 mm in diameter as material of the utility tunnel, and based on construction of the Central Avenue, the boxes for underpinning the Jinbin Light Rail Line were used to connect the utility tunnel. The design of the utility tunnel is introduced, including the section form, pipeline layout, foundation treatment method, waterproof measures, joint treatment, node treatment, auxiliary facilities and so on, which accumulates experience for construction of utility tunnels.
