摘要研究目的:为了进一步提升高速列车旅客乘坐舒适度，在加快改进高速列车性能的同时，更要注重高速铁路线路的设计与优化。为此，针对高速铁路线路参数与舒适度关系进行系统的分析和研究。研究结论:(1)建立了基于线路参数的舒适度评价模型，并确立了相应的评价区间;(2)根据《高速铁路设计规范(试行)》(TB 10621—2009)进行线路参数设计时，既要考虑线路的实际地形及工况，同时还要兼顾旅客舒适度的要求，选择合理的平、竖面曲线参数，才能设计出相对比较合理和旅客满意的线路;(3)通过对基于旅客舒适度的平面曲线半径设计与优化理论的分析和研究，得出了不同设计速度下的平面曲线半径最小推荐值;(4)该研究成果可为今后高速铁路线路设计与优化提供指导。

Abstract：Research purposes:To enhance the passengers ride comfort on the high-speed trains, the design and optimization of high-speed railway lines should be paid much attention to as well as speed up improving performance of high-speed trains. Therefore, the relationship between the comfort and line parameters of high-speed railway has been systematically analyzed and researched.
Research conclusions:(1) The evaluation model of comfort based on line parameters has been established and the corresponding evaluation interval has been determined. (2) According to code for design of high speed railway (trail), during line parameter design, not only the practical landform and working conditions should be considered, but also the ride comfort ought to meet the needs of passengers. Thus, a relatively reasonable line can be designed by choosing plane and vertical curve parameters. (3) After the analysis of the design and optimization of plane curve radius based on the comfort of passengers, the recommended minimum of plane curve radius under different running speed can be obtained. (4) The research results can provide better guidance for the design and optimization of high-speed railway lines in future.

Key words： high-speed railway dynamics comfort evaluation line parameter optimized design
