摘要
本文对线性工程中线的组成形式进行分析和总结,提出组件式方法:中线线型由直线、圆曲线、缓和曲线组成或者及其组合,并对该方法提出中线任意点的坐标计算和方位角推算的数学模型。
The composition analysed and summarized the organization forms of line-type project centre line, and proposed the component method: centre-line line-type makes up by straight line、circular curve、transition curve or their associations, and if a point is on the centre line ,the method puts forward a mathematics model to calculate the point’s coordination and azimuth angle..
