瓮马铁路南北延伸线引入都匀地区方案研究

通过分析都匀地区既有铁路现状及规划铁路,结合瓮马铁路货物流向,提出了瓮马铁路南延线引入黔桂线的必要性。结合都匀地区地形、城市规划和自然保护区范围,研究了瓮马铁路在黔桂线的前方站(都匀北站)或黔桂线绿荫湖站设置交接场引入都匀地区的方案,考虑到运营管理分解划分明确,减少折角运输,一次性建成南北直通通道,吸引国铁直通车流等因素,宜采用设置都匀北站交接场的方案。根据线路引入既有黔桂线接轨点的不同,对双线区间接轨方案、新都匀站站房同侧引入方案和新都匀站站房对侧引入方案进行分析,从工程量、工程投资、运输组织、施工难度及风险、投资建设模式等方面比较,得出双线区间接轨引入都匀地区方案最优。

Program of Introducing North-South Extension Line of Weng Ma Railway Into Duyun Area

Based on the analysis of the existing railway situation and planned railway in Duyun area, combined with the freight flow direction of Weng Ma railway, the necessity to introduce the South extension line of Weng Ma railway into Guizhou Guangxi railway is put forward. Combined with the terrain, urban planning and the scope of Nature Reserve in Duyun area, this paper analyzes the scheme of setting up transfer yard at the front station(Duyun North Station) of Weng Ma railway line or lvyinhu station of Qiangui line to lead into Duyun area. Considering the clear division of operation management, reducing the angle transportation, the North-South direct passage built at one time to attract the through train flow of national railway, Duyun north Station handover scheme is better than another scheme. According to the different connection points of the line leading into the existing Guizhou Guangxi railway, this paper analyzes the double track section connection scheme, the same side introduction scheme of xinduyun station building and the opposite side introduction scheme of xinduyun station building, and compares the engineering quantity, project investment, transportation organization, construction difficulty and risk, investment and construction mode, etc., and concludes that the scheme of double track indirect track leading into Duyun area is the best.
