摘要:
坡段长度是高速铁路重要的技术参数之一，影响到高速铁路的安全性和舒适性。本文通过理论分析、动力仿真及对比分析国内外取值等方法，从不同工况下的受力情况、列车运行的平稳性、经济适用性等方面分析研究，提出最小坡段长度应不小于450 m，且不同坡度对应最小坡段长度宜根据竖曲线半径和相邻坡度代数差予以计算。最后对最大坡段长度予以研究，并建议最大坡度为12‰时，最大坡段长度不受限制；最大坡度为15‰时，最大坡度地段的坡段长度不宜大于9 km；最大坡度为20‰时，最大坡度地段的坡段长度不宜大于5 km。
Abstract:
The slope length is one of the important technical parameters of the high speed railway, which affects the safety and comfort of the high speed railway. In this paper, through theoretical analysis, dynamic simulation and comparative analysis of domestic and international value methods, on the basis of stress conditions under different working conditions,the train running stability and economic applicability analysis and research, the minimum slope length should not be less than 450 m, and the minimum slope length corresponding to different slopesshould be calculated according to the vertical curve radius and the adjacent slope algebraic difference.Finally, the maximum slope length is studied, and it is suggested when the maximum slope is 12‰, the maximum slope length is not restricted; when the maximum slope is 15‰, the maximum slope length should not be more than 9 km;when the maximum slope is 20‰, the maximum slope length should not be more than 5 km.
