北京动车段出入段线建设规模及能力适应性分析

Adaptability Analysis of Scale and Capacity of the Entrance & Exit Depot Line of Beijing Multiple Unit Depot

研究目的:出入段线能力是决定动车段内设备能力能否得到充分运用的关键因素之一。本文以北京动车段为例,根据预测的客车开行方案,仿真铺画列车运行图;在满足动车组检修作业要求的前提下,运用计算机仿真技术,模拟分析动车组综合运用计划,确定各时段出入段线动车组出入次数;提出动车段出入段线的运输组织方案和能力计算办法,为动车段的勘察设计提供一些有价值的研究成果。研究结论:根据出入段线的运输组织方案,对照分析其在最有利和最不利条件下的通过能力与动车组出入段次数,确定出入段线能力的适应性及能力加强措施方案;分析得出全天存在4个小时段范围内2条出入段线能力不能满足运输需求,因此建议北京动车段设3条出入段线,各线均按双方向追踪运行设计。

Research purposes： The capacity of the entrance ＆ exit depot line （EEDL） is one of the key factors whether the ability of multiple unit depot can get full use . To optimize efficiency of facilities in depots, adaptability analysis of scale and capacity of the EEDL was conducted with an example of Beijing multiple unit depot, which is based on estimated train operation scheme and maintenance arrangements of electric multiple unit＇s （EMU） maintenance. EMU operating schedule with maintenance arrangements was simulated by train working diagram system, where the traffic volume of EMUs on EEDL can be obtained. Finally, this paper puts forward the scheme of transportation organization and the calculation method of carrying capacity. Valuable research results are provided for the survey and design of the multiple unit depot. Research conclusions： According to the scheme of transportation organization of EEDLs, comparison analyzing the condition of the best and worst about the carrying capability and the in and out of times of the EMU, confirming the adaptability of EEDLg transportation ability and giving the measurement to improve the capacity of its. Analysis of it, we can see that four one - hour time period per day the capacity of two lines can not meet the transport needs. Therefore, we suggest that EEDL of Beijing multiple unit depot should be set up three lines and every line should be designed to double -direction fleeting operation.
