摘要
避险车道是一项重要的安全设施,对预防长大下坡路段由于刹车失灵引起的交通事故具有重要的作用。本文通过实车足尺试验,研究了碎石道床避险车道对车辆阻尼效果与车辆质量、驶入速度以及避险车道纵坡的关系,确定了碎石道床避险车道对车辆的平均阻尼系数,并进而提出了避险车道的长度计算公式,为我国公路避险车道设计提供了有效的实验数据和参考依据。
The Truck Escape Ramp （TER） is very important for safe operation of large trucks on long down-slope section.Through a series of flail-scale vehicle tests, this paper analyses the relationship between the rolling resistance and the truck mass, entering velocity, the TER slope. Then, the formula of calculating the length of TER are brought forward, including the average value of the rolling resistance on gravel arrester bed. And this provides valid test data and reference for the design of TER in our country.
