Research on the Reconstruction Plan of Existing Railways in Complex Urban Areas
Research purposes:The construction of existing railways is relatively early,mostly built as roadbed,occupying the core position of the main urban area of the city.With the development of cities,the problem of existing railways obstructing urban traffic and causing fragmentation of urban areas is becoming increasingly prominent.In order to adapt to urban planning and development,optimize the urban transportation network,and reduce the cost of municipal road construction,this paper takes the renovation project of the Xiaoshan urban section of the Shanghai-Kunming Railway as an example to study the renovation plan of existing railways in complex urban areas.Research conclusions:(1)The existing railway renovation plan in urban areas should be coordinated and consistent with the overall urban planning and future development.(2)Detailed analysis of the impact of existing railways on the development of urban areas and urban transportation network were presented with the necessity of reconstruction project construction proposed.(3)Based on the characteristics of the project,the existing railway situation,and the influence of control factors such as the overall layout of the hub,a comprehensive study is conducted to determine the scope and type of renovation plan for the project.Multiple schemes are compared to determine the implementation plan and construction transition plan for the project renovation.(4)This study can provide reference for the study of existing railway renovation projects in similar urban areas.
