南京地铁4号线青龙车辆基地出入线方案研究

Study on Arrival and Departure Track Project of Qinglong Vehicle Maintenance Center of Nanjing Metro Line 4

南京地铁4号线青龙车辆基地出入线,原设计方案(方案1)接轨于桦墅站,该车站规模大,对周边河流、铁路均有较大影响,衍生工程较多,工程投资高,实施难度较大。文章通过深入研究,将出入线接轨站调整至仙林东站(方案2),在不影响行车功能要求的前提下,方案2在线路条件、运营条件、协调工作、车站建筑面积、周边环境适应性等方面均得到不同程度的优化与提升,取得了较好的效果。

The Nanjing Metro line 4 has the Arrival and Departure Track Project for Qinglong Vehicle Maintenance Center, the original design scheme （scheme 1） connects the tracks at Huashu station. The station is large in scale, have a greater impact on the surrounding rivers and railways, will generating more projects, with high project investment, and difficult implementation and rollout. Through in-depth study, the paper makes optimization and upgrading in the line conditions, operating conditions, coordinate work, the station building area, and the surrounding environment adaptability at varying degrees without affect the train running function requirements as the premise, by only adjusting the scheme 2 for the access track connecting the Xianlin station, good results have been and achieved.
