在任意控制点测设缓圆曲线

Measuring Curved Line at Any Control Point

缓圆曲线在线路测量中经常使用 ,测量员应了解如何正确计算曲线上任意点的坐标 ,在实地快速计算点位坐标并进行精确 。

The gradual changed curved line is often used in route survey . Surveyor must know how to correctly calculate the coordinate of any point on the curved line. It can raise the surveying work's efficiency that the surveyors calculate coordinate and precisely set stakes in the field.
