摘要
为实现山区高速公路路线设计安全、经济和保护环境,以高速公路交通调查资料为基础,应用汽车动力学原理,提出对山区高速公路车辆上坡行驶的最大纵坡按照理想最大纵坡、缓和坡段纵坡和一般最大纵坡划分的概念,并对纵坡及坡长限制提出建议值。该成果可以指导山区高速公路纵断面设计,并为技术标准的制定提供参考依据。
For the safety, economy and environment protection in mountain-expressway alignment design,based on the traffic volume survey of expressway, the concepts of the ideal maximum longitudinal gradient,transition grading gradient and general maximum longitudinal gradient were put forward through the analysis of vehicle's dynamics. The value of longitudinal gradient and grade length limitation were put forward for reference in mountain-expressway design and technique criterion establishment.
