摘要
当前关于城际铁路折返能力的研究,往往以单方向折返运输为主,不能与城际铁路网络化、公交化、小交路、多方向的运营特点相适应。为将两方向折返站折返能力的研究成果应用于实际设计工作中,本文通过收集大湾区城际铁路作业参数、北京全路通信信号研究设计院集团有限公司CRH6A型动车组车辆参数等大量真实数据,将仿真计算结果应用于图解法和横道图分析折返作业流程,结合长三角地区“四网融合”示范性工程南浔站,进行运行数据分析和经济技术比选。研究结果表明,站前折返站型折返列车作业间隔时间较短,切割正线,列车在区间等候进站的可能性大;站后折返站型折返列车作业顺畅,折返与通过列车作业交叉干扰小,但折返作业时间较长,折返能力小。因此,折返作业密集车站宜采用站前折返站型,通过列车较多的车站宜采用站后折返站型。本研究可为城际铁路折返站折返能力计算及站型布置提供参考。
Current research on the turnback capacity of intercity railways often focuses on one-direction turnback operations,which is not compatible with the operational characteristics of intercity railways,including networking,public transit-oriented service,short-haul,and multi-directional operations.To apply the research results on turnback capacity for two-direction turnback stations to practical design work,this paper collected extensive data such as operational parameters of the intercity railways in the Guangdong-Hong Kong-Macao Greater Bay Area and vehicle parameters of CRH6A multiple units from CRSC Research and Design Institute Group Co.,Ltd.Through simulation calculations,a detailed analysis of the turnback operation process was conducted using graphical methods and schematic diagrams,combined with Nanxun Station—the demonstration project of“four network integration”in the Yangtze River Delta region.The research indicate that the station-front turnback layout results in shorter intervals between turnback train operations but requires crossing the main line,increasing the likelihood of trains waiting in the interval before entering the station.The station-rear turnback layout ensures smooth turnback train operations with minimal interference between turnback and through train operations,but it has a longer turnback duration and lower turnback capacity.Thus,stations with intensive turnback operations should adopt the station-front turnback layout,while stations with more through trains should adopt the station-rear turnback layout.This paper can provide a reference for calculating the turnback capacity and designing the station layout of intercity turnback stations.
