摘　　要：曲线外轨超高是高速铁路重要的技术参数之一,其取值影响列车运行的安全性及舒适性。本文针对俄罗斯莫斯科至喀山高速铁路,采用理论分析、仿真分析及数据对比分析的方法,在速度目标值400 km/h且兼顾货运的前提下,从列车安全性、舒适性等方面出发,结合国内外高速铁路对外轨超高的取值,对该参数取值进行分析和研究,并得出结论:在单一高速模式下,有砟轨道和无砟轨道取值分别是160、180mm;在高、中速列车共线运行模式下,有砟轨道和无砟轨道取值均为160mm。The superelevation of the curved outer rail is one of the important technical parameters of high-speed railway,and its value affects the train operational safety and riding comfort.Aiming at the high-speed railway from Moscow to Kazan in Russia,this paper adopts the methods of theoretical analysis,simulation analysis and data comparison analysis to study the value of this parameter under the premise of speed target value of 400km/h,taking into account the freight transport,the train safety,comfort,and the high-speed rail at home and abroad on the superelevation of the curved outer rail.This study concludes that under the single high-speed mode,value is 160 mm for ballasted track and 180 mm for ballastless track,and under the high-speed and medium-speed train running mode,the value for both ballasted track and ballastless track value is 160 mm.
