公路平面线形的连续性及评定方法

On the Consistency of Highway Horizontal Alignment and Method of Evaluation

公路线形的连续性对于行车安全、舒适、经济均有重要意义。本文介绍了国外关于公路平面线形连续性的研究情况,比较了几种不同的评定平面线形连续性的方法,在此基础上提出了适用于我国情况的评定公路平面线形连续性的方法。按这一方法评定线形设计,可发现速度不连续处,从而对线形进行调整,以保证行车顺畅、速度连续、增加行车安全性和舒适性。并提出了进一步研究的建议。

In this paper,the state of the art of the consistency of highway horizontal alignment study abroad as well as a methods of the consistency evaluation suitable for China are presented.With the evaluation of alignment design as means, the speed inconsistency can be found out so that the alignment can be adjusted accordingly,resulting in the elimination of the inconsistency to ensure the comfor- tableness and safety of driving and travelling.Finally,the further research works are suggested.
