【摘要】 本文的选题,是针对我国大型编组站图定兑现率较低的现象提出的。以铁路第六次大面积提速调图为背景,本文根据编组站列流规律的不同将编组站分为三种类型,即列流叠加型编组站、列流互补型编组站和列流主方向型编组站。本文重点从旅客列车密集开行、“五定”班列和直达班列的开行、旅客列车晚点运行、“天窗”维修四方面分析产生不均衡运输的原因,并说明各种原因对不同类型编组站产生的影响以及对编组站内部各项作业(分为到解子系统和出发子系统两部分)产生的影响。通过对上述影响的分析及对传统编组站能力计算公式体系的分析,表明空费系数经验公式已经与现场实际不符,进而引进阶段不均衡系数和密集时间段两个参数对编组站能力计算公式体系进行优化,并提出针对不同列流类型的编组站应采用不同的不均衡系数。本文应用随机过程理论,从编组站到解子系统和出发子系统两部分分析密集时间段,根据密集时间段推导出阶段不均衡系数,以求得改进传统编组站能力计算公式体系;并辅以丰台西站为例验证改进后公式体系的应用性,提出针对不均衡运输造成编组站图定兑现率低的改进措施,只有实现客货分线运行才能彻底解决不均衡运输对编组站带来的影响。本论文包括图20幅,表23个,共参考文献70篇。更多还原

【Abstract】 The subject selection of the dissertation focuses on the phenomenon of the lower realization rate of operations in large marshalling yard. Based on the background of the sixth railway speed-up, marshalling yard can be classifed into three types by the different flow of freight train, namely marshalling yard with overlapped flow, marshalling yard with complementary flow and marshalling yard with main stream direction flow.The dissertation analyzes the reasons for unbalanced transport from four aspects: the CDB’s of intensive passenger trains, the CDB’s of "Five Scheduled" trains and the through trains, train delay and clerestory maintenance, followed by their influence on the different types of marshalling yard mainly including operation at arriving-disintegration subsystem and departure subsystem.With the analysis of the influence of unbalanced transport and traditional marshalling yard formula system, the dissertation shows that the empirical formula of coefficient cannot meet the operational requirements. Therefore, two parameters are introduced into it, that is: the ratio of the equivalent number of arriving/departure trains in intensive time to the equivalent number of arriving/departure trains on average in a day and time-intensive.The dissertation gives marshalling yard based on different types has different unbalanced ratio.Applying stochastic processes theory and using the unbalanced ratio calculated from time-intensive, the dissertation accomplishes the optimization of formula system on capacity of marshalling yard based on unbalanced transport about arriving-disintegration subsystem and departure subsystem in intensive analyzing periods. Then the dissertation takes Fengtai West Station as an example to testify the application’s efficiency of improved formula system, after which improvements on the low realization rate of marshalling yard is given. At the end, the dissertation conludes that passenger and freight-dedicated lines can completely eliminate influence on marshalling station brought by unbalanced transport. The dissertation includes twenty figures, twenty-three tables and seventy references.更多还原
