摘要
在高等级公路路线设计中,路线交叉连接部的线形设计是至关重要的。为使路线交叉连接部处纵面线形平顺过渡,介绍了一种纵面坡度设计方法。其计算简单、准确、可靠。
The alignment design of route cross - connect part is vital in the highway alignment design. This paper introduces a method of longitudinal slope design for vertical aligmnent smoothly transition. This method is simple, accurate and reliable.
