黔桂线扩能改造工程主要技术标准研究

Research on Main Technical Standards for Upgrading of Guizhou-Guangxi Railway

研究目的:本文介绍黔桂铁路(贵阳—柳州)的线路走向和工程概况。其中重点介绍扩能改造措施及主要技术标准研究,扩能方案的比选、限制坡度、以及提速改造,速度目标值、正线数目的比选,工程实施效果等,以期对电气化铁路的扩能改造提供借鉴。研究结论:电气化Ⅰ级铁路、单线预留复线,柳州—洛满段增建二线。限制坡度:6‰,双机13‰,牵引质量3800t。柳州至金城江段按160km/h速度目标值设计,金城江至龙里段按140km/h速度目标值设计,并酌留余量。

Research purposes：This paper introduces the alignment and the general upgrading of Guizhou-Guangxi Railway （Guiyang-Liuzhou）,including the upgrading measures,research on main technical standards,the comparison and selection of upgrading schemes,ruling gradient,speed target value and number of main track,as well as upgrading effect,for the purpose of providing the reference to the upgrading of electrified railway.Research conclusions：The Guizhou-Guangxi Railway is upgraded as Grade I electrified railway with singkle track,reversing condition for double tracks.The additional second track from Liuzhou to Luoman will be built.The ruling gradient is 6‰ and the ruling gradient is 13‰ in the section with double locomotive traction.The driving load is 3 800 t.The 160 km/h speed target value is desined for the Liuzhou-Jinchengjiang section and 140 km/h speed target value is designed for the Jinchengjiang-Longli section with some design margin.
