| 摘 要： | 卵形曲线作为一种比较新的曲线形式在高速公路立交平面线型中,现越来越多地采用,而卵形曲线坐标的计算在现有相关书籍中却又很少提到,这就为施工中的坐标计算及放样增加了较大难度,为解决此难道,我在实践中通过对缓和曲线坐标的计算加以分析并结合理论知识,总结出了卵形曲线坐标的计算方法和技巧。本文将主要阐述卵形曲线的主要参数计算以及卵形曲线上任一点坐标的计算方法。

| Abstract: | The oval curve took one kind of quite new curve form in highway grade separation plane linear,presently more and more many uses,but the oval curvilinear coordinate computation very little mentioned actually in the existing correlation books,this increased the great difficulty for the construction in coordinates computation and the lofting,is solves this,I in reality through analyze and unify the theory knowledge to the transition curve coordinates computation,summarized the oval curvilinear coordinate computational method and the skill.This article mainly elaborated the oval curve main parameter computation as well as the oval curve take office a coordinates computational method. |

| Keywords: | Oval curve Curve essential factor Coordinates computation |
