摘要
龙腾路下穿隧道作为成都市射线快速路网系统的其中一部分,也是二环路改造项目的一个重要节点。隧道位于龙腾路—大石路,横穿二环路,地下管网复杂,路口车流量大,道路红线宽度狭窄。从工程概况、现状概况、方案设计等方面对隧道设计方案进行了研究,比较了框架同层布置、框架叠层布置、单向交通三个方案,分析了各自的优缺点,得出了最优方案,可供相关工程参考借鉴。
As a part of radial express road network system in Chengdu,Longteng Road Tunnel is also an important node in the reconstruction project of No.2 Ring Road.The tunnel is located underneath Longteng Road-Dashi Road,and crosses No.2 Ring Road.The underground pipeline network is complex,the traffic flow is large at the intersection,and the red line width of road is narrow.The article studies the design scheme of tunnel from the engineering situation,present situation and scheme design in order to achieve the best scheme,which can be referred for the similar projects.
