市域铁路车辆基地总平面设计研究

Study on general layout design of urban region railway vehicle base

市域铁路客流潮汐现象明显,早晚高峰尤为突出,这些特点导致市域铁路车辆运用相较地铁存在明显差异,因此需要针对性地研究适应市域车辆运用特点的车辆检修体系。车辆基地总平面设计作为车辆检修效率和经济性的重要决定因素,需进行重点研究。文章针对市域铁路车辆运用特点研究“检修集中,停检分离”模式下的车辆基地检修效率和经济性问题,利用离散事件系统仿真方法量化不同总平面方案下车辆基地检修能力,并对咽喉区平行径路参数和总平面布置方式适应性进行分析,提出库前设置存车线的总平面布置方案,以解决2级2场总平面方案中咽喉区平行径路通过能力制约车辆检修能力的问题。

The tidal phenomenon of urban region railway passenger flow is obvious,especially in the morning and evening peak hours.These characteristics lead to the obvious difference in the use of urban railway vehicles compared with the metro vehicles.Therefore,it is necessary to study the vehicle maintenance system to adapt to the characteristics of urban region vehicle use.As an important determinant of vehicle maintenance efficiency and economy,the general layout design of vehicle base needs to focus on the general layout scheme of urban railway.Based on the characteristics of urban railway vehicles,this paper studies the maintenance efficiency and economy of vehicle base under the mode of Centralized Maintenance and Separation of Stop and Inspection,it simulates the maintenance capacity of vehicle base under different general layout schemes based on discrete scenario model and analyzes the adaptability of throat and bottleneck track parameters and general layout mode,and proposes the general layout scheme of storage track for vehicles before departing depot to solve the problem of throat capacity restricting vehicle maintenance capacity in the general layout scheme of two levels and two yards.
