新建铁路引入成都枢纽方案研究

Study on Scheme of Introducing a Railway into Chengdu Hub

成都枢纽是我国铁路网的关键节点和骨干枢纽。为研究某铁路引入成都枢纽方案,综合考虑枢纽客货运布局及总图规划、城市发展规划、客流特点、新线引入对既有线干扰等因素,采用多因素分布研究的方法,对引入站选择及线路走向方案开展系统研究。经综合比选,推荐采用可贯通东西向干线铁路、动车组径路灵活、线路引入对枢纽影响小、符合城市规划与发展要求的引入天府站方案;在引入天府站基础上,进一步研究线路走向方案,选取工程投资节省、兼顾工业园区运输需求、配套基地设置条件好的经寿安方案作为推荐方案。研究成果可为类似工程项目提供借鉴和参考。

Chengdu hub is a key node and backbone hub in China’s railway network.In studying the scheme for a railway into this hub,this paper systematically assessed the optional introduction stations and track alignments through multifactor distribution study,taking into account the hub’s layout of passenger transportation and freight and general layout planning,the city’s development planning and passenger flow characteristics,the interference of introducing the new line on existing lines among other factors.After comprehensive comparison,it is recommended to introduce Tianfu Station.In this scheme,the line enables through-connections with the east-west mainline railways,offers flexible EMU routing options,has less impact on the hub,and aligns with the city’s planning and development objectives.Based on Tianfu Station,this study further examined the track alignment options,and recommended the route via Shou’an,which will save project investment,meets the transportation needs of industrial parks,and has favorable conditions for setting supporting base.The findings can provide reference for similar projects.
