连续开行高等级客车对单线半自闭区段能力影响分析

Analysis on the Influences of Continually Dispatching High-Rank Passenger Trains to the Capacity of Single Line with Semi Auto-Block

以达成线成都—遂宁单线半自动闭塞区段为例,通过计算机编图软件模拟分析,研究了在繁忙时段连续开行高等级旅客列车对全段通过能力和旅行速度的影响。总的研究结果表明高等级列车的连续开行对全线通过能力没有显著影响,同时对高等级列车连续开行采用不同时间间隔时,在列车速度、扣除系数等指标的影响方面也给出了一些具体结论。

Taking Chengdu-Suining single line, the semi auto-block sectionof Da-Cheng line as example, with the aid of simulated analysis by computertrain-graph generation software, the paper studies the influences of continu-ally dispatching high-rank passenger trains during busy hours to the throughcapacity of whole section and to the travel speed. As an overall result, thecontinuous high-rank passenger trains will not have notable impact to thethrough capacity of whole line. In the meanwhile, it comes up with some de-tailed conclusions for the influences to train speed and coefficient of removalwhen continually dispatching high-rank passenger trains at different interval.
