摘要
重载铁路由于列车轴重的增加,对线路的破坏影响较大。改善线路的基本参数,特别是减缓线路的限制坡度、加大最小曲线半径,是各国改造重载运输线路、适应列车轴重提高的重要方面。本文通过研究各国重载线路的参数,以及参考国内第一条重载铁路——大秦线的线路参数,结合我国铁路的实际情况,对我国的重载线路提出建议性参数。
Heavy-haul railway has a great destructive effect on railway line because of the increased axle load. Improving thebasic parameters of line, especially decreasing the ruling grade of line and increasing the minimum curve radius are the importantaspects for each country to reconstruct heavy-haul transportation lines and adapt to the increase of train axle load. The essay putsforward prepositional parameters for Chinese heavy-haul railway lines by researching the parameters of heavy-haul railway linesin each country and in combination to the parameters of the first heavy-haul railway in ChinaDatong-Qinhuangdao line, andcombines with the actual situation of Chinese railways.
