| 摘 要： | 本文主要论述了与驼峰计算长度有关的3个问题:1.峰顶的合理位置.认为,峰顶设在连接峰顶平台与加速坡竖曲线的始端较为合理;2.峰顶至第1分路道岔尖轨尖端最小距离的确定.提出了两种计算方法,并建议采用模拟的经验公式进行计算;3.点连式驼峰计算点位置的确定.提出了打靶区段长度的确定原则和计算点位置的确定方法.

| Abstract: | Three topics about the calculated length of hump are discussed in this paper: 1.The reasonable position of hump crest.The more reasonable position of hump crest is the point Where the hump platform connects with the vertical curvature of accelerating grade. 2.Determination of the minimum distance between the hump crest and the first point of branch switch tongue.Two computational methods,together with a suggestion that it is better to use the imitated experience formula,are pro- posed. 3.To determine the position of calculated point of hump for point connec- ting type.The principle for determining the length of shooting section and the method of determining the position of calculated point are given. |
