线路分方向选择限制坡度及长大下坡道一直都是铁路设计和运营中关注的问题。文章从运量预测、制动安全、适应地形条件、工程技术经济、工程实施难度、运输组织适应性等方面综合分析,得出久永铁路采用长大下坡是安全和合理的结论。

For a long time,it is the key issues to choose the slope limitation and long and large downhills considering its direction for railway.By in detail analyzing the respects to forecast of traffic volume,brake safety,adaption of terrain conditions,project technique and economic conditions,project implementation difficulty,applicability of transport organization,etc.,this paper drew a conclusion that adopting long and large downhill in Shuangliuzhen-Yongwen section of Jiuchang-Yongwen railway was safe and rational.
