样条函数在公路设计纸上定线中的应用

Application of Spline Function to Paper Location of Highway Design

目前 ,在公路设计纸上定线中 ,对离散点的拟合方法大都采用直线形法和曲线形法 ,这两种方法是用直线、圆曲线去靠近尽量多的离散点 ,然后将直线与圆曲线直接相接或利用缓和曲线连接成为连续光滑的平面线形 ,本文在这两种方法的基础上提出用样条函数拟合纸上定线中的离散点 。

In the paper location of highway design, the fitting methods of discrete points adopt almostly the straight line way and curve way. On the basis of the two methods, the discrete points of paper location fitted by spline function are presented, and the formulas and examples given.\;
