| 摘 要： | 公路施工及检测中经常需要计算中线外某点至中线的距离或对应的里程，本文推导缓和曲线段任意测点的投影归算方法。由缓和曲线几何模型建立测点所对应的曲线长方程式，再采用牛顿法进行解算。该方法数据处理严密且简单实用，已在编程计算器上实现。

| Abstract: | The calculation is necessary for determining the distance of any point to midline or the relevant mileage in construction and check of highway.A reduction method for transition curve is deduced in this paper. The equation of curve length for the stake is established by geometrical model of transition curve and is calculated by Newton method.This calculation method is precise,simple and functional.It has been carried out by pocket calculator. |
