摘　　要：利用道路中线上任意里程桩号的坐标和切线角计算公式,建立其横断面直线方程式;分析了视距曲线的数学特征,建立了对应的视距直线方程式;将两方程联合求解,采用逼近方法,编写了相应的计算程序,从而完成任意里程桩号的横净距计算。Based on the expressions of calculating the coordinate and direction angle of the random position on the road alignment,the linear equation of the transverse section was established. The analyzing mathematical characters of the stadium curve,the corresponding linear equations were obtained. With the two equations the nettransverse distance of the random position can be calculated by a gradual way and calculating program.
