湘桂线永州至柳州段增二线与新建双线方案研究探讨

Discussion on the Scheme of the Second Line and the New Double Line of Yongzhou-Liuzhou Section of Xianggui Line

湘桂线是广西、海南及粤西地区东出与北上主要骨架铁路线,由于修建历时远久,既有线能力已经不能满足运营需求,急需进行扩建改造。根据运量预测,湘桂线永州至柳州段通道内双线即可满足运输能力需求,但增建二线又存在既有线利用率低,施工干扰大,运输组织单一等问题,因此有必要对新建双线进行研究。本文就永州至柳州段增二线、新建双线方案以及组合方案进行研究比较,选择确定最佳方案,为类似项目提供借鉴意义。

The Xianggui Line is the main skeleton railway line in the east and north of Guangxi, Hainan and western Guangdong. Due to the long-term construction,the existing cable capacity can no longer meet the operational needs,and it is urgent to carry out expansion and reconstruction. According to the traffic forecast,the two lines in the channel from Yongzhou to Liuzhou in the Xianggui line can meet the transportation capacity demand. However, the second line of the second line has problems such as low utilization rate of the cable,large construction interference,and single transportation organization. Therefore,it is necessary to build new Two lines for research. This paper compares the Yongzhou-Liuzhou section of the second line,the new two-line plan and the combination plan,and chooses the best plan to provide reference for similar projects.
