摘　　要：最小曲线半径是铁路线路设计中的一个重要参数,对列车速度方案和线路成本具有很大影响。本文根据更高速度目标值(400/380 km/h)对更高速度条件下最小曲线半径取值进行了理论计算和仿真分析,提出了更高速度条件下最小曲线半径的参考取值。根据研究结果建议:设计速度380 km/h时,最小曲线半径推荐8 500 m,一般条件下为7 500 m;设计速度400 km/h时,最小曲线半径推荐9 000 m,一般条件下为8 500 m。The minimum curve radius is an important parameter in railway line design,which has a great influence on train operation speed and railway line cost.According to a higher speed target value（400/380 km/h）,the minimum curve radius under condition of higher speed has been calculated and simulated,and the reference value of the minimum curve radius under condition of higher speed has been proposed.The results show that the recommended value of minimum curve radius is 8 500 m when speed was 380 km /h and the recommended value is7 500 m under normal conditions,and the recommended value of minimum curve radius is 9 000 m when speed was400 km/h and the recommended value is 8 500 m under normal conditions.
