摘　　要：分析高速铁路开设周期天窗的必要性,运用"斜率分析法",给出了在开设2 h检查天窗、且矩形天窗分段数分别为2、3、4时,上下行夕发朝至列车开行数量的计算方法,并总结天窗分段数对夕发朝至列车"可行区域"的影响规律。最后,以京广高速铁路为例,计算结果表明,当采用"北京西—石家庄—长沙南—广州南"4个矩形天窗分段时,上下行夕发朝至列车数量可达到最大值。Based on analyzing the necessity of setting up periodical Maintenance window for high- speed railways, by using ＂slope analysis method＂, this paper provides the calculation method of evening-departure ＆ morning-arrival trains operation number on up and down line when setting up 2 h inspection window and the window sectional number was divided into 2, 3 and 4. The paper also summaries the influence principle of window sectional number on ＂feasible section＂ of evening- departure ＆ morning-arrival trains. In the end, taking Beijing-Guangzhou high-speed railway as example, the calculation result shows when applying 4 rectangular Maintenance window sections of ＂Beijing West-Shijiazhuang-Changsha South-Guangzhou South＂, the number of evening-departure ＆ morning-arrival trains on up and down line could reach to a maximum.
