摘要
城际铁路区段通过能力是衡量铁路运输部门能否合理利用线路和是否满足客流需求的重要依据。本文针对城际铁路时段客流特性,考虑不同时段下列车正点可靠性的差异性以及天窗产生的三角区对"时段长度"的影响,分时段选取列车运行组合模式、计算区段通过能力。引入时段"空费时间"对各时段通过能力进行衔接,以计算最终全日城际铁路通过能力。通过算例,计算该某城际铁路区段下行方向通过能力以验证该方法的准确性。研究考虑列车服务水平的城际铁路通过能力,对于制定列车开行方案,提高列车满载率和提高列车服务水平具有指导意义。
Intercity rail section capacity is an important basis for measuring whether the railway transportation department can reasonably use the line and whether it meets the demand of passenger flow. This paper considered the passenger flow characteristics during the intercity rail period, the differences in the reliability of the following vehicle punctuality at different time and the effect of the triangulation generated by the sunroof on the 'period length'. On this basis, it selected the train operation combination mode and calculated the section passing capacity in different time periods. In addition, the 'air time' period was introduced to connect the capacity of each period to calculate the capacity of the final full-city intercity railway. Through calculation examples, the ability to pass through the downward direction of an intercity railway segment was calculated to verify the accuracy of the method. Studying the ability of intercity railways with considering the level of train services has guiding significance for formulating train plans, increasing train full loading rates and improving train service levels.
