摘要
结合福州市琅岐环岛路二期地下综合管廊工程,阐述了综合管廊的设计要点,详细介绍了管廊的工艺设计、结构设计及施工方法,并阐述若干设计体会:一是对于软土地基上建设综合管廊,建议管廊结构基底与道路路基处理形式尽量一致;二是利用顶管穿越河道,应足够重视顶管节段之间以及顶管与沉井之间的防水设计;三是设计软土路基上的综合管廊应考虑路基施工对综合管廊的影响。
Taking Underground Utility Tunnel Project in the second phrase of Langqi Huandao Road in Fu Zhou as case study,the key design points of Underground Utility Tunnel were expounded,moreover,the process design,structural design and construction method of Underground Utility Tunnel were introduced in details. Some design experience could be obtained,including： 1. For the Underground Utility Tunnel built on soft soil foundation,the treatment method of the foundation of Underground Utility Tunnel is suggested to use the same method as subgrade. 2. The waterproof design between top tunnel segments or top tunnel and caisson should be paid attention to,when the top tunnel is used to cross river. 3. The influence of subgrade construction on the Underground Utility Tunnel should be considered in the design of Underground Utility Tunnel built on soft soil foundation.
