摘　　要：研究目的:包西铁路通道为"包柳通道"的重要组成部分,本文针对本段铁路目前现状和功能对既有线扩能改造的建设规模进行研究论述。研究结论:从包柳通道在路网中的地位及其作用来看,最终将形成一条双线大能力通道。为充分发挥其通道的整体运输能力,本段扩能改造时北段包头至大保当一次新建双线,速度目标值为160km/h(预留200km/h);中段大保当至延安既有线增建二线,速度目标值为160km/h;南段延安至西安一次新建双线,速度目标值为160km/h(预留200km/h),既有线维持不变形成三线格局。包西线先期建成双线既解决了煤炭运输外运的运能不足问题,又解决了直通运量能力不足的问题,符合包柳双线大能力通道的总体规划。Research purposes： The Baotou- Xi＇an Railway Corridor is an important part of Baotou- Liuzhou Railway Corridor. This paper gives an introduction to the current situation of the Baotou - Xi ＂an Railway and studies the upgrading scale of this existing railway. Research conclusions：In view of the role and effect to be played and made by this railway, the Baotou - Liuzhou Railway will become double - line railway at last with large traffic capacity. In order to give full play to the whole traffic capacity of this railway corridor, when upgrading this railway, the double- line from Baotou to Dabaodang in the north section should be built with the target speeds of 160 km/h and 200 km/h in future, the second line from DaDaodang to Yan＇an in the middle section should be built with the target speed of at 160 km/h, and the new double - line from Yan＇an to Xi＇an in the south section should be built with target speeds of 160 km/h and 200 km/h in future. The existing line remain its original to form the three -line pattern. The early built -up double -line from Baotou to Xi＇an will not only solve the problem of insufficient traffic capacity for outwardly transporting coal, but also solve the problem of the insufficient through traffic capacity. So this pattern accords with the general planning of Baotou - Liuzhou double - line with large traffic.
