基于不均衡运输的编组站能力计算方法探讨

Computation of Capacity at Marshalling Yard Based on Imbalanced Transport Circumstances

通过分析列车到达不均衡对编组站作业的负面影响,结合编组站作业系统的特点,把编组站的工作时间分为忙、闲和普通三个阶段,以编组站的核心内容解体作业作为计算能力的基础,并且考虑了其它设备能力的影响,提出用编组站通过能力、编组站车流结构条件通过能力和驼峰小时解体能力三个概念来计算编组站的能力.与传统的编组站能力计算方法相比,突出了重点,计算结果相对能更好地反映不均衡运输条件下编组站的实际工作状况.

The article investigates the factors affecting the capacity at marshalling yard after the train speed increased in China. The imbalanced character of goods train flows is found to be the major factor. According to the arrival and departure regularities of the goods train flows, a method of dividing per day into the busy, the free and the ordinary stages is presented. Also, a new system based on the changed operations and the devices factor is proposed to describe the capacity at marshalling yard. The computation results of Shijiazhuang marshalling yard show that our method provides more accurate and feasible ways to analyze the new changed operations and capacity at marshalling yard.
