重庆至利川铁路是规划建设的沪-汉-蓉客运通道中最后建成的一段。通过从地形地貌、工程投资、运输组织、工期、施工风险等方面，对不同的坡度方案进行分析比选，确定渝利铁路合理的最大坡度。本段铁路采用限制坡度9‰，加力坡18.5‰的方案。利用大功率机车更适应地形、地貌，工程投资较省，长大隧道少，工程的安全风险低、工期合理，能满足客、货车牵引质量和速度要求，运输组织合理，运营支出较省。

Chongqing-Lichuan railway is a finally-completed section of Shanghai-Wuhan-Chengdu passenger transporta-tion channel. According to landform, engineering investment, transportation organization, construction period and con-struction risk, different gradient schemes are compared to determine a maximum reasonable gradient of Chongqing-Li-chuan railway. This line uses the limiting gradient of 9‰, boosting slope 18. 5‰. High power locomotive is more suit-able to the terrain and landform, which can reduce engineering investment, long tunnels and engineering safety risk, make construction period reasonable, satisfy the requirements of passenger freight train traction quality and speed. In ad-dition,it can reduce operating expenses.
