轨道交通车辆段出入线接轨方案设计探索

Discussion on Design of Track Joining of Departure and Arrival Track of Vehicle Depot of Urban Rail Transit

研究目的:车辆段出入线接轨方案研究是轨道交通前期设计中的一个重要课题,本文通过对无锡地铁1号线西漳车辆段出入线的一站接轨方案和两站接轨方案进行比较后,从接轨站车站规模、线路条件、行车干扰程度、折返以及出段作业效率、建设投资等因素出发,综合分析,最终确定了最合理方案。研究结论:(1)出入线应本着方便运营、优化平纵断面条件,减少与正线的行车干扰,提高列车折返、出入段作业效率,降低运营成本等要素来选择合适的接轨方式。(2)在轨道交通设计中,应结合车辆段的段址,正线线路条件、车站规模,行车,运营,投资等多种因素,选择相对合理的接轨方式。有条件时可结合段型布置,实现列车调头转向功能。(3)在选择车辆段出入线的接轨方式时,应从区域规划,项目建成后的社会效益,经济效益等多方面考虑,确定最合理方案。

Research purposes： The research on the track joining of the departure and arrival track of the vehicle depot is a very important work in the prophase design. In this paper, through comprehensively analyzing and comparing the schemes for the one - station track joining and two - station track joining of the departure and arrival track of the Xizhang Vehicle Depot of Line 1 of the Wuxi metro, the analysis is made from areas of the scale of the station where the track joins, track conditions, the interference degree on the traffic, the turn - back operation, the operation efficiency of the train departing the depot and the construction investment so as to decide the most reasonable scheme. Research conclusions：The factors of the easy operation, optimization of the plane and vertical sections conditions, reduction of the traffic interference on the main track, improvement of the operation efficiencies of the train turning back and departing and arriving at the depot and reduction of the operation cost should be considered for selection of the track joining mode of the departure and arrival track. In addition, the factors of the depot site, the main track conditions, the station scale, the traffic conditions, the operational conditions and investment should be considered to select the reasonable track joining mode in the design of the urban rail transit. According to the layout of the station, the train has the function of changing direction if possible. When selecting the track joining mode of the departure and arrival track of the depot, the factors of the regional plan and the social and economic benefits also should be considered to decide the most reasonable scheme.
