摘要
研究目的:通过对既有线扩能提速改造各种建设方案的分析,从线路设计能力、运输组织、提速效果、土地利用、与既有线的干扰、工程投资等方面综合考虑,确定既有线扩能提速改造的建设方案。研究结论:通过对几条既有铁路各种单线扩能方案、新建单线扩能方案、增建二线并部分改造既有线方案、分步建成双线和一次新建双线方案等分析比较,可以得出一次新建双线方案具有工程投资省、经济效益好、运输质量高、施工对既有线干扰小,为社会经济的进一步发展和路网建设提供了较为广阔的空间等优点。故既有线扩能提速改造建设方案宜采用一次新建双线方案。
Research purposes： Based on the comprehensive considerations of the design track capacity,traffic organization,speed-increasing effect,land usage,interference to the other existing lines and engineering investment,the analyses of the upgrading schemes of existing railway line are made for deciding the final upgrading scheme.Research conclusions：From the comparison and analysis of the previous upgrading schemes of some existing railway lines,such as reconstruction of single track,additional construction of the second line with partial upgrading of the existing line,construction of double track step by step and construction of double track by one time,it is concluded construction of double track by one time has features of saving construction cost,getting good economic benefits,high traffic quality,less interference to the other existing railway lines,and provding the wide space for further economic development and railway network construction.So the scheme of construction double track by one time should be adopted for upgrading of existing line.
