Research on minimum curve radius and maximum slope value of india high speed rail

最小曲线半径和最大坡度是铁路线路设计的一个重要参数,对列车速度方案和线路成本具有很大影响。分析了世界各国高速铁路线路平面技术标准,并经过理论计算确定本线平面最小曲线半径采用7 000 m,困难条件下采用5 500 m。结合350 km/h高速铁路动车组性能及沿线地形适应性分析,最大坡度采用20‰坡度既有利于发挥动车组性能,又能较好地适应本线地形,因此本线采用20‰的最大坡度。

Minimum curve radius and maximum slope are important parameters of railway line design,which have great influence on train speed scheme and line cost.In this paper,the plane technical standard of high-speed railway line in the world is analyzed,and the minimum plane curve radius of this line is 7 000 m by theoretical calculation.Under difficult condition,5 500 m is adopted.Analysis of 350 km/h high-speed railway EMU along with performance and adaptability of terrain,the maximum slope slope by 20 per thousand is conducive to play the perform-ance of EMU,and can adapt to the line of terrain,so this line by maximum gradient of 20 per thousand.
