摘要
随着高速铁路行车密度的加大,高速铁路线路能力日趋紧张,传统的以固定追踪间隔时间排布运行图及进行运行方案调整的方式较为粗放,很难准确反映列车追踪情况。为充分利用列车运行图能力,在阐述列车追踪间隔时间分类的基础上,根据追踪列车在站停站与否,对精细化的列车追踪间隔时间计算方法进行分析,考虑前行列车与后续列车在站停站差异及列车加减速性能差异,提出最小列车追踪间隔时间的计算方法,最后进一步探讨不同速度等级列车追踪时间计算方法,为提高高速铁路日常运营组织灵活性提供理论参考。
With the increase of the train density of high-speed railway, its capacity is in shortage. The traditional calculation of the train tracking as a regulating interval to arrange train diagram and adjust the train running program can not reflect the actual tracking of the trains. In order to make full use of the train diagram ability, the classification of the interval time of the train tracking is expounded. According to whether the train stops at the station, the precise train interval calculation method is analyzed. Consider the stop pattern difference of the first train and the second train as well as dynamic performance differences such as acceleration and deceleration, the calculation formula for minimum interval is proposed. Finally, the calculation method for the train tracking interval of different speed levels is further discussed. It provides the theoretical support for improving the flexibility of daily operation of high-speed railway.
