摘要: 本文对立交平面线形设计中线形相交的计算,采用逐渐趋近法求解.这种方法,计算简单、明确,收敛速度快;对于编有中桩坐标计算程序的任何线形,其解算方法极易在计算机上实现.

关键词: 平面线形, 线形相交计算, 逐渐趋近法, 点到中线的垂距

Abstract: This paper uses successive approximation methods for calculating alignments' intersections horizontal alig nment design.This method is simple to calculate and definite.It has fast convergence speed,Any alignment uchich has calculating program of coordinate of middle pegged-point this calculating method is easy to perform in computer.

Key words: horizontal alignment, calculating alignments' intersections, successive approximation, the vertical distance from dot to median line
