摘　　要：编组站是铁路技术作业的基层生产单位,在车流组织中起着关键作用.首先着眼于确定单双向系统选择的技术条件,并以此为基础,定量研究反向改编列车对单向系统及折角车流对双向系统各自的影响,从车流结构角度得出影响选择的技术因素.在上述研究基础上,以单向三级三场和双向三级六场为代表,构建能力约束条件下的典型单双向系统的择优比对模型,并通过徐州北编组站进行实例验证,从中看出,从车流结构入手,根据各种车流在编组站所消耗总费用的高低来进行站型选择不仅切实有效,而且经济科学,同时,这也为全面定位编组站的规模和布局提供了一种科学有效的决策手段.Marshalling station is a fundamental unit of railway technical operation, and plays a key role in wagon flow organization. This paper first puts forward technical items in type selection, and then makes quantitative study of the influence of reversing trains on unidirectional Marshalling stations and angular traffic flow in bidirectional Marshalling station respectively, from which some relative technique factors are acquired in the aspect of wagon flow structure. Afterwards, this paper presents typical station type selecting model by taking unidirectional three-stage/ three-yard Marshalling station and bidirectional three-stage/six-yard Marshalling station as representation. At last, the experiment to demonstrate the effect of the method is conducted on Northern Xuzhou Marshalling Station proves that station type selecting by means of comparing the total waste of wagon flow in the Marshalling station from the view of wagon flow structure is not only effective but scientific and it provides a scientific and effective decisionmaking measure for determining the scope and layout of Marshalling station.
