摘　　要：目前,我国高速铁路日常综合维修主要采用分段垂直矩形天窗的形式,天窗对长途跨线列车的影响远远大于本线列车。通过对相邻天窗分段交错时间采用图解法进行分析,研究发现:天窗分段的长度和交错时间是影响顺向跨线列车运行的主要因素,列车运行时分最长的天窗分段限制了分段垂直矩形天窗对顺向跨线列车的影响范围,其影响范围等于天窗限制区段的天窗开设时长与运行时间之和。在对三个相邻天窗分段开设的情况进行研究的基础上,得出了最小天窗影响时段的天窗交错时间取值范围。At present, China high-speed railway comprehensive day-to-day maintenance operates mainly in the form of segmented vertical rectangular window.The influence of the window on the cross-line transport organization is greater than that on the window setted line transport organization. This article analyzed the window staggered time with graphic method. The study found that the window section length and window staggered time were the main factors influencing the consequent cross-line train operation. The window section with the longest train-running time limited the affected area of the segmented vertical rectangular window＆amp;nbsp;for the cross-line transport organization. Its scope was equal to the sum of window opening time and train-running time in the window limited section. Based on analyzing the setting windows in three adjacent lines, and a reasonable range of the window staggered time for the window minimum affected time was put forward.
