缓和曲线加宽内外边线的计算方法

Calculation Method of Inside and Outside Line of Easement Curve Segment

随着高速公路的快速发展,缓和曲线段的加宽越来越受到重视,但是加宽后的内外边线坐标和曲线长的计算非常麻烦,关于这方面的介绍也非常少,故通过理论计算,提出内外边线的坐标和曲线长的计算公式,具有一定的参考价值。

As the rapid development of highway, the widening of easement curve segment is more and more at a premium, but the calculation of coordinates and length of inside and outside line is very complex, however, the introduction of this content is very little. Therefore, the study on calculation of coordinates and length of inside and outside line in details with corresponding formulas being deduced on theory, has certain reference value.
