兰新通道嘉峪关及嘉峪关南站扩能改造方案研究

Renovation Plan for Jiayuguan and Jiayuguan South Station of Lanzou-Urumqi Railway Corridor

兰新通道嘉峪关铁路地区点线能力不协调,造成兰新线运输能力释放不足,兰新高速铁路能力富余较大,成为制约兰通道运输效率的主要问题。通过对兰新通道现状、嘉峪关站及嘉峪关南站的分析,提出兰新通道嘉峪关及嘉峪关南站扩能改造3个方案:方案I:嘉峪关站扩能改造,方案Ⅱ:嘉峪关南合场方案,Ⅲ:嘉峪关南并场。经综合比选,推荐采用方案Ⅲ,有效解决了嘉峪关站到发线能力不足及客、货列车交叉干扰问题,提高了兰新通道整体运输效率。

The unbalanced capacity between stations and the line in the Jiayuguan Railway Area of Lanzhou-Urumqi Railway Corridor leads to insufficient release of transportation capacity of Lanzhou-Urumqi Line and abundant capacity of Lanzhou-Urumqi High-Speed Railway,which has become the main factor restricting the transportation efficiency of Lanzhou-Urumqi Railway Corridor.Based on the analysis of the current situation of Lanzhou-Urumqi Railway Corridor,Jiayuguan Station and Jiayuguan South Station,three renovation plans of Jiayuguan and Jiayuguan South Station are proposed:Plan I:capacity expansion and renovation of Jiayuguan Station;Plan II:merging of yards at Jiayuguan Station;Plan III:Parallel yards at Jiayuguan South Station.After comprehensive comparison and selection,Plan III is recommended,which effectively solves the problems of insufficient capacity of arrival-departure track and interference between passenger and freight trains at Jiayuguan Station and improves the overall transportation efficiency of Lanzhou-Urumqi Railway Corridor.
