本文首先从提高一级二场编组站的编组场尾部能力这个中心环节,对编组场尾部牵出线的四种布置形式,从编组能力,运营条件和工程数量等方面进行分析计算,得出了编组场尾部采用长牵出线设计为好的初步结论。然后,对一级二场编组站的四种图型,从布置特点、改编能力、图型的弹性、是否保持一级二场编组站特有的优点,运用条件、发展和占地等方面,进行了全面的分析研究,得出了编组场头部拉直图型是一级二场编组站图型中最优的初步结论。供在设计时参考。
In this paper, from the perspective of improving the capacity of the tail end of the two marshalling stations at the first stage, this paper analyzes and calculates the four arrangements of tail lines at the tail end of the marshalling yard, and analyzes the marshalling capacity, operating conditions and the number of projects. The tail end of the long pull line design as a good preliminary conclusion. Then, from the four characteristics of the first marshalling yard, from the characteristics of arrangement, adaptability, flexibility of the figure, whether to maintain the unique advantages of the first marshalling yard, the application conditions, the development and the land occupation, etc. A comprehensive analysis of the study, concluded that the head of straightening group coding straightening pattern is a map of the first two marshalling best preliminary conclusions. For reference in the design.
