京沪高速铁路列车运行图能力影响因素分析

Analysis of Influence Factors of Train Graph Capacity of Beijing-Shanghai High-speed Railway

通过分析京沪高速铁路运行图能力的影响因素,系统地建立了运行图能力影响体系,据此提出了五个可行的有助于京沪高铁运行图能力提升的措施。首先通过理论分析初步建立了影响体系;其次结合高速铁路的运行特点对运行速度、停靠次数与停站时间、列车越行等影响因素进行了单因素影响分析以及交叉影响分析,以此建立了单因素影响函数;再次,建立了综合影响模型,并以京沪高铁为例对模型进行了阐述;最后,通过综合影响模型对影响因素本身及其对运行图能力的影响程度进行了定量表达,从而为运行图能力的提升提供一定的借鉴。

In this paper, through analyzing the influence factors of the train graph capacity of the Beijing-Shanghai high-speed railway, we established systematically the corresponding influence system, proposed accordingly five feasible measures to improve the train graph capacity of the Beijing-Shanghai high-speed railway. First, through theoretical analysis, we built up the preliminary influence system, then in light of the operational characteristics of the high-speed railway, conducted the single factor analysis and crossover factor analysis on such influence factors as running speed, number and length of stop, overtaking etc., and built the single factor influence function. Next, we built the comprehensive influence model and elaborated on it in connection with the Beijing-Shanghai high-speed railway. At the end, we represented quantitatively the influence factors per se and their extent of effect on the train graph capacity of the railway.
