摘　　要：研究目的:针对襄阳北编组站衔接线路主要技术标准不一致、没有预留上行系统条件等问题,对编组站上下行系统作业分工、平面布置、折角车流、线路疏解和施工过渡等方面进行深入研究和探讨,提出新的思路。研究结论:(1)襄阳北站上下行系统采用不平衡作业分工,可充分利用既有设施和设备,减少对运营的干扰;(2)采用反到进路将西北向折角列车引入上行出发场进行列车增减轴作业、上下行系统各3条调车线兼交换线组成交换场进行折角车流处理,可有效缩短列车在枢纽内的作业行程,减少机车取送车次数以及对其他技术作业的干扰,提高车站作业效率和能力;(3)施工过渡设计减少联锁软件过渡次数,可有效缩短施工周期,消除安全隐患;(4)本研究结论可供新建或改建编组站方案借鉴。Research purposes: In view of the inconsistency of the main technical standards of the connecting line of Xiangyang North Marshalling Station and the lack of reserved uplink system conditions, this paper makes an in-depth study and discussion on the division of operation work, layout, corner traffic flow, line distribution and construction transition of the uplink and downlink system of the marshalling station, and puts forward new ideas.Research conclusions:(1)The uplink and downlink system of Xiangyang North Station adopts non-balanced division of work, which can make full use of existing facilities and equipment and reduce the interference to operation.(2)The reverse arrival route is used to introduce the North-West corner traffic flow into the uplink departure yard for axle increase and decrease. The exchange yard is composed of three shunting and exchanging lines of the uplink and three shunting and exchanging lines of downlink system for corner traffic flow treatment, which can effectively shorten the operation travel of the train in the hub, reduce frequency of locomotive pick-up and delivery trains and the interference to other technical operations, and improve the operation efficiency and capacity of the station.(3)Reducing transition times of interlocking software in construction transition design can effectively shorten the construction cycle and eliminate potential safety hazards.(4)The research conclusion can be used for reference for the scheme of new or reconstructed marshalling station.
