摘要
为适应不同地区居民出行的差异经济承受能力,研究在客运专线出现的高速和普速列车共线运营的新运输组织模式下,无砟轨道超高设置的适应性问题。针对不同速度的高速和普速列车混跑模式,通过对欠、过超高容许值的分析、限值检算,超高与轮轨的关系,曲线半径与超高的关系,以及超高顺坡率的调整和计算,结论为:曲线的轨道超高设置按照250km/h速度的均衡超高来确定可满足大部分列车通过需求,并且缓和曲线全段设置超高顺坡。
To adapt to the affordability discrepancy of inhabitants in different regions during travelling, this paper researched the adaptability of ballastless track super-elevation under the newly-appeared transport organization mode in which both the high-speed trains and normal-speed trains run together on the same railway passenger dedicated line. Meanwhile, focusing on the mixed transportation mode at different speeds for high-speed trains as well as for normal-speed trains, this paper analyzed and checked the allowable values of super-elevation deficiency and super-elevation excess, and researched the relationships between super-elevation and wheel track, super-elevation and curve radius. Also, this paper adjusted and calculated the rate of super-elevation slop. Finally, this paper came to the conclusions： （a） the curve track super-elevation should be arranged in accordance with 250km/h balanced super- elevation, because it can satisfy most of trains＇ passing through; （b） the super-elevation slop should be arranged along the whole transition curve.
