摘要
高速铁路列车追踪间隔是衡量高速铁路通过能力的重要标准之一。为实现3min追踪间隔,在分析列车不同追踪间隔原理的基础上,给出列车区间追踪间隔、列车出发追踪间隔、列车到达追踪间隔等列车间隔时间计算方法,对速度、闭塞分区长度、线路坡度、咽喉区限速、咽喉区长度等关键影响因素进行仿真分析,提出主要制约因素包括信号系统、线路条件、列车性能,为新线路设计提供有效参考。最后,在保持线路横纵断面不变的前提下对既有线路进行优化,通过提升列车性能或改变线路限速的方式,提出高速列车追踪间隔的优化策略,并通过仿真算例验证,实现3min追踪间隔。
The train tracking interval is one of the important measurements of high-speed railway＇s passing capacity. Based on a review of the theories on tracking intervals, with the goal of the ＂3-min tracking interval＂, this paper has first obtained the methods of calculating the interval time between： railway stations, departing trains and arriving trains. Then, the paper has carried out a simulation analysis of the key influencing factors on tracking intervals such as speeds, block lengths, track gradients, lengths and speed limits of key throats. Based on the simulation results, this paper has shortlisted the major constraints on track designs： the signal system, the track conditions and the trains＇ performance, which are expected to serve as reference points for future track designs. On the other hand, in order to realize the ＂3-min tracking interval＂ for the existing high-speed railways with fixed cross and vertical section conditions, this paper has proposed a strategy to optimize tracking intervals through improving train performance or changing the speed limits, which has been verified with simulation results.
