摘　　要：为满足旅客出行需求,提升高速铁路通过能力,对比已有能力计算方法,提出列车开行结构特征对高速铁路能力计算的重要性,采用模型优化方法,构建高速铁路区段通过能力计算模型,并建立区段通过能力影响因素敏感度体系,应用区段能力计算方法,开展各因素对区段能力提升的影响程度分析,提出区段能力提升有效措施。研究结果得出:缩短追踪间隔时间对区段能力提升影响最大。实际应用时,建议有限采用提高动车组列车定员和缩短列车追踪间隔时间的措施,其次采用统一运行速度或调整列车停站频率和越行结构来改变列车开行结构等措施。To meet the travel needs of passengers and improve the carrying capacity of high speed railways, this paper compared the existing capacity calculation methods and highlighted the importance of the characteristics of train operation structures to the calculation of high speed railway capacity. A calculation model for the carrying capacity of high speed railway sections was built by the model optimization method, and a sensitivity system of influencing factors of section carrying capacity was created. The calculation method of section capacity was applied to analyze the influence of various factors on section capacity improvement, and effective measures for section capacity improvement were put forward. The results show that shortening the tracking interval has the greatest impact on section capacity improvement. In practical applications,measures were proposed such as increasing the train capacity of electric multiple units(EMUs),shortening the train tracking interval, unifying the operation speed of trains, adjusting the train stop frequency and overtaking structure to change the train operation structure.
