摘要
文章结合长沙至昆明铁路客运专线贵州、云南段,分析研究艰险山区高速铁路相邻车站两端的平曲线、断面设计及超高设置。认为凸型纵坡最有利于停站列车通过相邻车站两端曲线的最低速度;采用凹型坡,原则上应尽量采用较小的坡度,且曲线距车站中心控制在4km以上;相邻车站两端的曲线半径应尽量大。
In the paper, in combination with Guizhou section and Yunnan section of Changsha-Kunming Passenger Dedicated Line, an analysis has been made on horizontal curve, profile design and curve superelevation setting of both ends of adjacent stations on passenger dedicated line in dangerous mountainous area. The analysis result shows that the convex longitudinal slope is most beneficial for stop train to pass the curve section of both ends of adjacent stations at lowest speed ; while if the concave slope is adopted in the design, in principle the small gradient shall be used as far as possible and the distance from curve to center control of the station shall be more than 4 km ; the radius of curve of both ends of adjacent stations shall be big as far as possible.
