湘桂铁路衡阳至柳州段扩能改造方案研究

A Study on the Capacity Expansion Plans of Hengyang-Liuzhou Section of Hengyang-Nanning Railway

为了提升湘桂铁路衡阳至柳州段运输能力,在对湘桂铁路衡阳至柳州段运量预测与能力适应性分析的基础上,对湘桂铁路衡阳至柳州段扩能改造方案进行研究。提出5个扩能改造方案方案,即单线自动闭塞改造、单线自动闭塞加提高牵引质量到3 000 t、单线自动闭塞加电气化改造提高牵引质量到4 000 t、单线自动闭塞加电气化改造提高牵引质量到5 000 t,以及增建第二线同步电气化改造并提高牵引质量到4 000 t,并对5个方案进行经济分析比选,最后建议选择单线自动闭塞加电气化改造提高牵引质量到4 000 t方案,为湘桂铁路衡阳至柳州段扩能改造提供参考。

In order to increase the carrying capacity of Hengyang-Liuzhou section of HengyangNanning Railway, this paper puts forward five options that are based on an estimate of the line＇s carrying capacity and an analysis of its adaptability： 1. Renewal of the automatic blocking sections of the single tracked railway; 2. Renewal of the automatic blocking sections of the single tracked railway with increased tractive tonnage to 3000 t; 3. Electrified renewal of the automatic blocking sections of the single tracked railway with increased tractive tonnage to 4000 t; 4. Electrified renewal of the automatic blocking sections of the single tracked railway with increased tractive tonnage to 5000 t; 5. Building the second electrified railway with increased tractive tonnage to 4000 t. Based on technical and economic comparison and seclection of the 5 plans, this paper concludes with the recommendation for the third one, which is expected to serve as a reference point for the capacity expasion project of Hengyang-Liuzhou section of Hengyang-Nanning Railway.
