摘　　要：双线电气化铁路综合维修天窗对区间通过能力的影响与牵引供电臂的设置密切相关。在研究Ⅴ型天窗对通过能力影响的基础上,引入天窗影响区概念,明确天窗影响构成因素的时间参数含义和计算办法。以陇海铁路天兰段为例,分别计算区段内各牵引供电臂构成的天窗对通过能力的影响,并通过实际模拟进行验算,确定天窗构成因素分析法计算的天窗影响通过能力符合实际,为准确计算双线区段区间通过能力提供了理论支持。For double-track electrified railway, the impact of maintenance window on the section carrying capacity is closely related to the configuration of traction feeding section. This paper studies the impact of Ⅴ-shape maintenance window on the carrying capacity, by introducing the impact area of maintenance window and defining the meaning and algorithm of the time parameters of the maintenance window impact factors. Taking the Tianshui-Lanzhou section of Lianyungang-Lanzhou Railway as an example, the impact of the maintenance window caused by the traction feeding section is calculated and then verified through simulation, which shows that the carrying capacity calculated with the maintenance window factor analysis method is in line with the actual situation. This study provides theoretical support for the accurate calculation of section carrying capacity of double track railway.
