重庆市新燕尾山隧道选线研究

新燕尾山隧道是重庆市快速路五横线的东延伸,其往东衔接渝黔高速扩能项目,是重庆市主城南部东西向的主要骨架道路,具有重要社会、经济效益。现从大范围的通道走廊进行比选,结合对隧址进行多方案论证,得出了规划燕尾山隧道应作为规划控制预留、新燕尾山隧道应尽快实施的结论,同时论证了新燕尾山隧道合理的线路方案。其成果可供类似山地复杂条件下城市隧道选线提供参考和借鉴。

Study on Route Selection of New Yanwei Mountain Tunnel in Chongqing

New Yanwei Mountain Tunnel is the east extension of the five horizontal lines of Chongqing Expressway.It connects the expansion project of Chongqing-Guizhou Expressway to the east.It is the main east-west skeleton road in the south of the main city of Chongqing with the important social and economic benefits.By comparing and selecting from the large range of channel,combined with the demonstration of many schemes for tunnel site,the conclusion is obtained that the planed Yanwei Mountain Tunnel should be reserved as the planning control,and New Yanwei Mountian Tunnel should be implemented as soon as possible.At the same time,the reasonable route scheme of New Yanwei Mountain Tunnel is demonstrated.The results can provide the reference for the route selection of urban tunnels under the similar mountainous complicated conditions.
