摘要: 本文介绍一种新的公路平面线形曲线型设计方法.该方法首先利用三次样条拟合的基本原理,绘制满足地形地物约束的徒手线,利用图形软件对生成的徒手线用直线和圆弧进行拟会,形成由一系列的直线和圆弧单元构成的线形骨架,然后根据直线与圆之间、圆与圆之间的相对位置.配置缓和曲线,并确定缓和曲线参数,最后采用线元设计法,敷设公路平面线形.
关键词: 公路平面线形, 三次样条拟合, 缓和曲线配置, 线元设计法
Abstract: This paper introduces a new curve method for designing highway horizontal alignment. After a hand-worked curve which meets the control of country is drawn by using the basic principle of 3-order spline curve. alignment sketch composed by a series of. tangency and arc is splined to form by using fig ure software. Then spiral curve is set between tangency and arc, or between.arcs. At last, a horizontal alignment is drawn by using the design method of alignment unit.
Key words: highway horizontal alignment, 3-order spline, setting spiral curve, design method of alignment unit
