本报告内容主要是对我国蒸汽牵引Ⅰ级新线铁路限制坡度最大值加以经济指标的分析。经分析,得到在复杂地形地区中适宜于单机或双机牵引的具体条件。并得到在单机牵引下合理的限制坡度,其结果在某些条件下最经济的限坡已经超出了目前设计规范所定数值。在研究过程中,计算了各种情况下,铁路运营费和其他经济指标的规律。这些规律在勘测路线,和选择限制坡度时都是有用的。经整理成曲线形式附在报告中。便于勘测路线的同志参考,如此可以节省路线选挥工作的时间。
The content of this report is mainly to analyze the maximum index of the grade of steep Grade I new railway for steam traction in China. After analysis, the specific conditions that are suitable for single or double traction in complex terrain area are obtained. With reasonable limits of slope under single-machine traction, the result is that the most economical slope-limiting under certain conditions has exceeded the values specified in current design codes. In the course of the study, the law of railway operating expenses and other economic indicators under various conditions was calculated. These laws are useful in surveying routes and in choosing to limit the grade. Sorted into a curve attached to the report. Easy to survey route comrades reference, so you can save the route selection work time.
