郑焦城际铁路开行普速列车曲线超高研究

Study on Curve Superelevation of General Speed Passenger Train on Zhengzhou-Jiaozuo Intercity Railway

研究高低速列车共线运行线路曲线超高设置对速度、舒适度的影响。以郑焦城际铁路开行普速客车曲线超高研究为例,分析超高参数设置原则,对不同速度组合方案下曲线超高进行计算,并相应检算舒适度,阐明合理设置曲线超高对减少曲线限速,提高舒适度,降低钢轨磨耗,节省运营成本的作用。

Taking the curve superelevation of general speed passenger train running on Zhengzhou-Jiaozuo intercity railway as an example,this paper analyzes the principle of curve superelevation parameter setting,calculates curve superelevation of different speed combinations,and checks the comfort level.The research concludes that reasonable curve superelevation can reduce curve speed limit,improve comfort level,reduce rail wear and save operating costs.
