本文根据汽车行驶的动力特性和在冰雪路条件下实测的摩擦系数,计算出汽车匀速和减速上坡时的最大爬坡能力。同时,确定出在纵向滑移稳定条件下公路最大可能使用的纵坡度值。经过比较,提出寒冷地区各级公路设计允许使用的最大设计纵坡的建议值。
In this paper, according to the dynamic characteristics of vehicle driving and the measured friction coefficient under the conditions of ice and snow road, the maximum climbing ability of the vehicle at the time of constant speed and deceleration is calculated. At the same time, the maximum longitudinal grade value that the highway can use under the condition of longitudinal sliding stability is determined. After comparison, the recommended value of the maximum design longitudinal allowable for highway design at all levels in cold area is proposed.
