对称基本型平曲线横净距精确计算的新算法研究

摘要

The paper studies the calculation method of Transverse spacing in the light of the basic model of symmetrical plane curre andPut forward a new simplified calculation method of transverse spac-ing That can find quickly and accurately calculation point through applying the characteristic of convex curve symmetrical basic horizontal curves have and the slope of the line of sight,this calculation method can calculate the transverse spacing of any point on the horizontal curves.calculation It has been worken out that calculation program can calculate the transverse spacing of any point on the horizontal curves ac-curately using VB6.%对对称基本型平曲线横净距的计算方法进行了分析研究，提出利用对称基本型平曲线属于凸型曲线的特点、应用视点连线斜率快速准确地寻找计算点位置的新的横净距简化计算方法，可对平曲线上任一点位进行较精确横净距的计算。应用 VB6编制了计算程序，可精确计算该型曲线任意位置时的最大横净距。
