双线铁路反向行车对正向线路通过能力和列车旅行速度的影响分析

通过对列车运行图结构分析,在确定旅客列车会车区和越行停留时间基础上,分别对不同等级反向列车产生的会车次数进行深入研究;运用列车组和价结构理论,对不同等级反向列车与不同正向列车组组合的情况下,对能力的影响进行分析。建立反向列车对正向线路通过能力和列车旅行速度影响的数学模型,分析其影响规律,认为铁路双线区段组织反向行车对线路通过能力和列车旅行速度都会产生一定的负面影响,并随列车开行数量和区间运行时间等影响因素的增加而增大。

Analysis of the Influence of Reversing the Operation to Trains on Double-track Railway upon Carrying Capacity and Traveling Speed

Based on the analysis of the constitution of the train working diagram, the confirmed the meeting station and the overtaking and standing time of the passenger trains, the paper analyzes the number of meetings of trains of different classes running in reversed direction, studies, with the train consist cost configuration theory, the influence on the carrying capacity by combined operation of trains of different classes in reversed direction as well as in normal direction. A mathematic model of the influence on the capacity and traveling speed is established to analyze the influence rule. The study concludes that on double-track railway, the reversed operation will result in negative influence on both capacity and speed. And this influence will increase with the number of trains operated on the section and the time used.
