摘　　要：该文在线路中线曲率概括模型的基础上 ,推出了任意点切线方位角计算通式和线路中线坐标计算的通用数学模型 ,它适用于直线、圆曲线和各种情况的缓和曲线中桩的坐标计算 。On the basis of the highway central line curvature general model, the paper gives the general formula for the random point tangent azimuth angle computation, and the general mathematical model for the highway central line coordinate computation. It suits to the center station coordinate computation for straight line, circular curve and easement curve under different conditions. It establishes a rigid basis for the coordinate method of laying out the highway central line.
