摘　　要：高速铁路列车运行图中预留的弹性时间较小,列车运行过程中发生扰动后易引发后向传播。目前,在扰动传播条件及相应的阻断技术方面,尚缺乏系统性的分析和研究。利用计算机仿真技术从微观角度分析了不同速度等级、不同闭塞分区长度等条件下的列车运行扰动传播问题,仿真结果表明:在列车出站加速过程中发生的扰动对追踪列车的发车影响较大;闭塞分区长度不同,触发扰动传播的阈值不同;在3min追踪间隔下,发生扰动传播时,前行列车的扰动累积附加走行时分均大于20s,表明列车从车站发车运行至区间后,前后列车的时空间隔有一定余量;针对扰动产生的影响程度,提出预留时空空闲带、优化车辆性能、推广自动驾驶等缓解和阻断扰动传播的措施和技术。The reserved flexible time in the train working diagram of high speed railways is relatively insufficient,which is easy to cause disturbance propagation during the train operation.At present,there is a lack of systematic analysis and research on train disturbance propagation conditions and corresponding blocking techniques.The computer simulation was used to analyze the train disturbance propagation under the conditions of different speed levels and block section lengths.The simulation results show that the disturbance caused by acceleration during train departure has a great impact on the departure of the following train.The thresholds of triggering disturbance propagation vary with the block section length.Under the 3 min tracking interval,when disturbance propagation occurs,the cumulative additional running time of the front train generating disturbance is all greater than 20 s,which indicates that there is a remaining interval in the space and time between the front and following trains after the trains depart from the station and run into the section.According to the influence degree of disturbance,the measures and techniques for alleviating and blocking disturbance propagation are proposed,such as reserving space-time free zones,optimizing vehicle performance,and promoting automatic driving.
