限制坡度是铁路线路纵断设计的重要指标;是决定设计区段牵引重量和机车类型的依据。因此,限制坡度选择的是否合理,对于节约铁路建设投资,提高运输效率,有着极为重要的意义。随着我国铁路基本建设重点的改变,既有线改造工程投资增多,对于如何确定限制坡度,是当前急待解决的问题。下面结合近年来在旧线改造中,遇到的有关限制坡度问题,进行粗略分析探讨,供作参考。
The limiting slope is an important indicator of longitudinal design of railway lines; it is the basis for determining the traction weight and locomotive type in the design section. Therefore, it is very important to limit the choice of slope to save investment in railway construction and improve transportation efficiency. With the change of railway infrastructure in our country, the investment in reconstruction of existing railway line has been increased. How to determine the limit of slope is an urgent issue to be solved urgently. Below with the recent years in the transformation of the old line, the problem of limiting the slope, a rough analysis to explore for reference.
