朱中线引入包兰线接轨方案研究

A Study on Plans for Connecting Zhujiayao-Zhongchuan Railway to Baotou-Lanzhou

随着兰州新区的快速发展,为解决兰州新区快速增长的运输需求,提高路网灵活性,需要增加兰州铁路枢纽兰新线与包兰线第二通路。在分析兰州铁路枢纽、朱中线、朱家窑站现状的基础上,结合包兰线车站分布情况及地形条件、朱中线线路走向、兰州新区发展状况,根据兰州新区东拓形成兰州铁路大北环的思路,分别研究朱中线在朱家窑站和白银西站引入包兰线的接轨方案,从运输组织、引入条件、工程投资、运输需求、新区规划等方面综合比较2个方案,最终推荐朱中线在包兰线朱家窑站接轨。

Building a second railway line besides Zhujiayao--Zhongchuan railway of Lanzhou Railway Hub is regarded as an important step to improve the transport capacity in the region that has a fast-growing demand. With a review of the local conditions, including Lanzhou Railway Hub, the current status of Zhujiayao-Zhongchuan rail line and Zhujiayao Railway Station, this paper outlines the local terrain features, the distribution of train stations along Baotao-Lanzhou rail line, the trend of Zhujiayao--Zhongchuan rail line, and the development of Lanzhou New Area. In line with the plan of expanding Lanzhou New Area eastward to form a big ring railway in the north part of the network, the paper puts forward two potential plans to connect Zhujiayao--Zhongchuan railway to Baotou-Lanzhou railway at either Zhujiayao Station or Baiyin West Station, which are compared from technical and economic aspects that include transport organization, connection conditions, project investment, transport requirements, and the layout of the New Area. In conclusion, the author recommends that the first proposal, getting connected at Zhujiayao Station, would be a better choice.
