泸定站特殊站型方案研究

Research on the Special Layout of Luding Station

泸定站位于高桥上,车站两端桥隧相接。本文结合桥隧工程条件以及车站的功能性,从正线分合修、车站规模、特殊货场的布置等方面对泸定站的特殊站型方案进行研究,并结合货车调车作业组织提出对站型的优化改进方案。最终建议泸定站采用正线分修、岛式站台的平面布置形式,车站设置4条到发线(含正线),在工程条件及投资允许的情况下建议在货场增加可供整列摘挂列车停靠的配线,或者在泸定站配备专门的调机,以优化调车作业时间。

Luding Station is located on a high bridge,connecting with tunnels at both ends of the station.Based on the bridge and tunnel engineering conditions and the station’s functionality,the special layout scheme of Luding Station is studied in this paper from some aspects,like station size,special freight yard layout and if the mainline is separate or combined.An optimization and improvement plan for the station layout is proposed according to the freight train shunting organization.In the end,it is suggested that the mainline combined and island-type platform layout is adopted for Luding station.The station has 4 arrival and departure lines(including the 2 mainlines).To optimize shunting operation time,considering the engineering conditions and investment,it is recommended to add tracks of freight yard appropriately,or deploy dedicated locomotive at Luding Station.
