本文通过曲率计算线路上各点的切线方位角及运用Simpson公式建立的线路中线坐标模型,讨论了地面点与线路中线相对关系的计算方法。
In this paper, the calculation method of the relative relationship between the ground point and the line centerline is discussed by calculating the azimuth of the tangential line at each point of the line and the line center line model established by Simpson formula.
