现行公路路线设计规范是针对一般公路编制的,其中一些指标并不适用于风景区道路设计。本文阐述了分析风景区道路最大纵坡取值的方法,并运用汽车动力学知识计算出以大客车为代表车型的景区道路最大纵坡的合理取值。文章得出的结论在一定程度上增加了风景区道路纵断面设计的灵活性。
The current highway route design code is for the general highway preparation, some of which do not apply to the scenic road design. This paper expounds the method of analyzing the value of the maximum longitudinal slope of the road in the scenic area and calculates the reasonable value of the maximum longitudinal slope of the scenic road with the bus as the representative vehicle by using the knowledge of vehicle dynamics. The conclusions drawn by the article have increased the flexibility of the design of the longitudinal section of the scenic area to a certain extent.
