摘　　要：格库铁路是南疆地区重要的出疆通道,于2020年开通运营,2021年运输能力已饱和。通过对比格库铁路运量构成、路网结构确定格库铁路运量增长的原因,以及其在路网中的重要作用。结合格库铁路作为单线铁路现状区间过长的特点,对增加会让站、复线及二者结合三种扩能改造方案的运输能力、工程投资、对既有线运营影响进行对比。研究表明,增开会让站方案具有工程投资少、建设工期短、对既有线运营干扰小等明显优势。采用该方案后,平图能力将由现状的15对/d提升至34对/d。本研究对于出疆通道结构布局、单线铁路扩能改造方案选择具有一定借鉴意义。The Golmud-Korla Railway is an important outbound channel in the southern Xinjiang,which put into operation in 2020.According to the calculation of the transportation volume and section capacity of Golmud-Korla Railway,the transportation capacity was almost full by the end of 2021.By comparing the composition of the transportation volume and network structure of the Golmud-Korla Railway,the willingness to increase the transportation volume of the Golmud-Korla Railway and its important role in the network were determined.The transportation capacity,engineering investment,and impact on existing line operation of three expansion and renovation plans,including adding meeting stations,double tracks,and combining the two,were discussed based on the characteristics that Geku Railway as a single-track railway with a long current section.The adding meeting stations plan has advantages in terms of low engineering investment,short construction period,rapid formation of transportation capacity,and minimal interference to existing line operations.By adopting this plan,the flat map capability will be increased from the current 15 pairs/d to 34 pairs/d.This study has a certain reference significance for the layout of the exit channel structure and the selection of the expansion and renovation plan for single track railways.
