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