摘要
既有城市轨道交通线路车辆一般采用固定编组的形式,因初期客流量较低,通常采用小编组车辆运营,中长期客流增加后,采用扩编改造的方式,但改造周期和费用较高,新旧车辆混编给检修维护工作带来困难,且城市轨道交通客流量具有早晚高峰的潮汐特征,市域快轨又具备市-郊差异化的客流体量特点,若考虑远期客流水平需配置长编组列车,但在初期开通运营和平峰期时乘车率低,造成部分列车闲置、空车运营等资源浪费,因此,亟需一种基于灵活编组运行的技术来解决上述问题.通过分析市域快线4辆编组、8辆编组、4+4辆编组混跑模式下与信号、站台、屏蔽门等土建接口存在的匹配问题,提出了不同场景下的解决方案和思路,给市域快轨线路的总体设计规划和各系统接口设计规范提供了参考方案,以实现车辆的灵活编组运行,获得更经济的运营成本.
Abstract
The trains running on existing urban rail transit lines are generally in fixed formation.Due to the small passenger flow volume at the beginning of service,the short formation is usually adopted for train operation.With the increase of passenger flow volume in middle term and long term,the formation will be extended but the transformation requires a long period and a high cost and the mixed formation of new and old cars will make the maintenance work more difficult.In addition,the passenger flow volume of urban rail transit has the tidal characteristics with morning and evening peaks and the passenger flow volume of the urban rapid rail is different in city and in suburb,therefore considering the long-term passenger flow level,it's necessary to allocate trains of long formation.However,as the riding rate at the beginning of service and in the off-peak period is lower,it will cause waste of other resources such as some trains in idle or running without passengers.Therefore,a technology based on flexible formation is in urgent need to solve the above-mentioned problems.By studying the matching problems of the 4-car train,the 8-car train and the train of 4+ 4 cars with the civil engineering interfaces such as signal equipment,platform and screen door in the mixed operation mode,this article proposes solutions and trains of thought for different scenarios and provides reference solutions for the overall design planning of city rapid rail lines and the design specification of different system interfaces in order to realize the operation of vehicles in flexible formation and obtain a more economical operation cost.
