摘要
公路线形设计是公路合理设计的关键环节之一,为有效控制公路平面、纵面线形设计的质量,文章在公路线形设计评价中引入了可能速度法,对线路设计中所确定的指标进行检查和修正,以确保公路线形设计的连续性、协调性以及安全性,并结合山区二级公路一段沿河路段线形设计实例,探讨了可能速度在公路线形设计中的具体应用方法与效果。
Highway linear design is one of key links in rational design of highway, in order to effectively control the linear design quality of highway plane and longitudinal surface, this article introduced the possible speed method in the evaluation of highway linear design,checked and corrected the indica- tors determined during route design, so as to ensure the continuity, coordination and safety of highway design, and then combined with the linear design example of a road section along the river of the secondary highway in mountainous area, it discussed the practical application method and effect of possible speed in highway linear design.
