铁路线路超限坡设置探讨

随着我国铁路线路技术条件的改善、机车功率的提高,既有线改扩建时,为了软化坡度、降低工程难度,可以考虑合理地使用超限坡。根据我国铁路现行标准中关于线路及机车牵引的规定,分析了在保证运输安全、满足运输能力的基础上,电气化线路改建设计中采用超限坡的可行性和必要性;讨论了采用超限坡的设计原则,并提出了超限坡的设计方法。

Tentative Study on the Design of Over-gradient Slope

With the improvement of line technical specifications and the increase of locomotive power,over-gradient slope may be designed to reduce the difficulty level for slope engineering when upgrading existing lines.Based on the standard of lines and locomotive traction,the paper analyzes the feasibility and necessity of using over-gradient slope when upgrading electrified lines without affecting operation safety and capacity,and also presents the design principles and methods for over-gradient slopes.
