世博会园区综合管沟沟槽支护体系设计及施工

综合管沟全称为"综合管线共同沟",以矩形箱涵的形式作为各种管线安装布设的载体,避免了今后增设管线对道路的开挖,方便维护管理。综合管沟相比常规箱涵有路线长、沟槽深、结构尺寸变化大等特点,沟槽支护体系的设计及施工必须充分考虑到上述特点。该文介绍了中国上海2010世博会园区综合管沟沟槽支护体系的设计与施工情况,可以为类似工程提供可借鉴的经验。

Design and Construction of Engineering Tunnel Supporting System in EXPO Site

The engineering tunnel is in the rectangle type of box culvert as the carrier for installing and laying various pipelines to avoid the excavation of the road if to add the pipelines in future,which is convenient for the maintenance management.The engineering tunnel has the characteristics of the longer route,deeper tunnel,more variable structural dimension and son than the conventional box culvert.The design and construction of tunnel supporting system must fully consider the above characteristics.The article introduces the design and construction of the engineering tunnel system in China Shanghai 2010 EXOP Site able to provide the experience for the similar projects.
