摘要
由于地形和经济条件的限制,山区公路不可避免连续长大下坡路段。为改善西藏山区公路连续长大下坡路段的交通安全状况,避险车道是目前解决连续长大下坡路段交通安全问题最为有效的工程措施。论文通过对载重汽车失控时受力分析,探讨车辆在长大下坡路段制动失效的原因和规律;据此对避险车道的长度、坡度设计进行了讨论。
Because of the topography and economic conditions,there are many continuous and long downgrades inevitably in mountainous roads.To improve the traffic safety situation of mountainous roads in tibet,the rescue lane is the most effective engineering measures.This paper,through the stress analysis of the car when it out of control,to discuss the reason and regular pattern of the vehicle＇s braking failure on the long and steep downhill path.Though this,the length and slope of the rescue lane is proved.
