隧道接线道路线位选线方案研究——以上海市龙水南路越江隧道为例

Research on Route Selection Scheme of Tunnel Connection Road:Taking Shanghai South Longshui Road River-CrossingTunnel As an Example

城市隧道设计是一个相对复杂的过程,需充分考虑各种客观因素。设计前需对该线位的隧道周边环境、地下管线分布、水文地质条件等情况进行全面调查和勘察分析,同时与现实情况相结合,保证设计的可实施性。为进一步明确特大城市越江隧道接线道路选线要点和原则,文章以上海市龙水南路越江隧道接线道路选线实践为例,重点从城市经济发展原则、交通网络体系、沿线敏感点、道路沿线旅游景观等方面阐述路线比选过程,总结特大城市越江隧道接线道路选线要点和重点原则,可为其他同类工程设计提供参考。

Urban tunnel design is a relatively complex process,which needs to fully consider various objective factors.Before the design,it is necessary to conduct a comprehensive investigation and survey analysis on the surrounding environment of the tunnel,the distribution of underground pipelines,hydrogeological conditions and other conditions of the line,and combine them with the actual situation to ensure the feasibility of the design.To further clarify the key points and principles of the route selection of the river crossing tunnel connecting road in megacities,taking the route selection practice of the river crossing tunnel connecting road in South Longshui Road in Shanghai as an example,the route selection process is mainly elaborated from the aspects of the principles of urban economic development,the traffic network system,sensitive points along the line,and the tourism landscape along the road,and the key points and principles of the route selection of the river crossing tunnel connecting road in megacities are summarized,which can provide reference for the design of other similar projects.
