本文以高速铁路天窗分段为基本研究单位,按照沿线途中大站将京沪高速铁路划分为若干天窗分段,分析天窗分段对列车运行的影响时间范围。在统计列车平均停站系数、停站时分和起停车附加时分等参数的基础上,计算列车一次停站的能力扣除系数以及天窗影响时间范围内通过能力的扣除值,得出京沪高速铁路在开设分段矩形天窗时线路通过能力的理论值以及限制区段。

The paper takes the segmented maintenance windows as the basic research unit. Beijing-Shanghai high-speed railway was divided into several segmented maintenance windows according to the major stations along the way, and the impact time ranges caused by the windows were analyzed, then, based on counting the parameters of train average time, stopping time, additional stopping and starting time and so on, the train stop deducting coefficients were calculated and the appropriate calculation method to get the deduction of the carrying capacity during the time frame affected by the maintenance windows was propsed. The theoretical capacity and the limiting section of Beijing-Shanghai high-speed railway could be got while the segmented rectangular maintenance windows was set on the line.
