高速铁路竖曲线设置误差分析

Setting Error Analysis on High-Speed Railway Vertical Curve

通过对传统竖曲线高程计算模型的分析,给出了竖曲线变坡点位置的确定方法及其对高速铁路坡面高程计算的影响,得出了以传统方法设置高速铁路竖曲线时误差的变化规律及提高计算精度的措施。对于现场施工和设计人员均具有一定参考价值。

By analyzing the model of traditional vertical curve,this paper proposes a method to determine location of the knick points in vertical curve and explains its effect on the calculation of slope elevation in high-speed railway.The changing rules of error can be concluded when using traditional method to set high-speed railway vertical curve and the actions to improve calculation accuracy are also proposed.It can provide reference for the field construction and designers.
