土耳其时速250km客货共线铁路最小曲线半径的研究

土耳其东西铁路干线拟按180～250 km/h速度目标值、客货共线铁路标准建设,按照中国先进、成熟的高速铁路标准和技术进行规划设计,重点研究时速250 km客货共线铁路的最小曲线半径。时速250 km客货共线铁路的最小曲线半径需要考虑高低速列车的匹配速度,速差越大,曲线半径越大;综合考虑舒适度指标及经济因素,土耳其时速250 km客货共线铁路的最小曲线半径一般值取4 000 m,个别最小值为3 500 m。

Research into Minimum Curve Radius of Mixed Passenger and Freight Railway with Speed of 250 km/h in Turkey

The transmeridional railway main line in Turkey was intended to be planed and designed under the speed target values of 180～250km/h with mixed passenger-freight traffic capacity according to Chinese standard of high-speed railway which is advanced and mature.This paper focuses on the researching of minimum curve radius of mixed passenger and freight railway with the speed of 250km/h.The paper thinks that the speed harmony between the high speed trains and the low speed trains should be considered because the larger the speed difference is,the larger the curve radius becomes.Considering the comfortableness and economy,the minimum curve radius of mixed passenger and freight railway with the speed of 250km/h in Turkey is determined as 4000 meter in general,and 3500 meter in exceptional circumstance.
