摘要
编组站的到达列流特征主要与衔接方向数、各衔接方向的技术特征、编组站与始发终到客运枢纽站的距离及编组站布置图的类型等因素相关。选择京广和京沪线上的多个编组站,通过对其技术作业图表的统计分析,将编组站列流到达特征归纳为叠加型、互补型和主方向型到达列流3种类型,根据列流到达强度将全天分为繁忙、空闲和普通3个阶段,在此基础上,采用CurveExpert曲线拟合软件按方向别对各阶段的列流到达时间间隔分布规律进行统计分析。结果表明:空闲期列流到达时间间隔的分布规律基本上符合Heat CapacityModel和Harris Model曲线拟合模型;普通期列流到达时间间隔分布规律基本符合Harris Model和Heat Capaci-ty Model曲线拟合模型;繁忙期列流到达时间间隔分布规律主要符合Harris Model曲线拟合模型。
The arrival regularity of the train flow in marshalling station is mainly affected by the number of its connecting directions, the technical characteristics of the connecting directions, the distance between marshalling station and railway passenger terminal station, and the type of marshalling station layout and so on. On the basis of analyzing technical working charts of a number of marshalling stations selected from Beijing--Guangzhou and Beijing--Shanghai railway lines, the arriving train flow as follows： superposed train flow, this paper summarizes three characteristics of reciprocal train flow and major direction train flow. Based on arrival intensity of train flow the whole day is divided into three phases： busy, idle and normal. According to the characteristics of the train flow, the arriving interval rule of the freight trains in all phases is processed and classified in connecting direction by CurveExpert. The results show that the arriving interval rule of the freight train basically tallies with Heat Capacity Model and Harris Model in idle phase, Harris Model and Heat Capacity Model in normal phase and Harris Model in busy phase.
