摘要
介绍通过坐标变换的方法导出高等级公路中平曲线上任意点在控制坐标系中的坐标计算公式 ,并配合PC—E5 0 0计算机计算程序 ,从而在任意控制点上采用极坐标法快捷、准确地放样平曲线上的详细点。
With the method of the coorinate transformation, the coordinate calculation equation of the arbitrary point of the top\|class highway in the control coordinate system is deduced and the detailed point of the plane curve will set out accurately and quickly in the arbitrary control point by the means of PC\|E500 computer program.\;
