摘　　要：近年来,超高车辆与桥梁限高架刮撞的事故时有发生,发生事故的主要原因有夜间视线不佳,车辆驾驶员未发现前方有限高架、车辆驾驶员发现限高架时距离较近,车辆制动不及、车辆驾驶员判断限高架的通过高度错误、车辆驾驶员通过限高架前方时注意力不集中等原因。通过对桥梁限高架进行缓冲碰撞的结构改进,可让限高架具有较大的提醒面积、限高架移动缓冲车辆的碰撞动能、活动板避免伤害等功能,可有效降低超高车辆与桥梁限高架刮撞概率、避免造成车辆和架乘人员损伤的事故。In recent years,the collision accidents of super high vehicles and bridge limited viaduct occur frequently.The main causes of the accidents are poor vision at night,the vehicle driver does not find the limited viaduct ahead,the vehicle driver finds the limited viaduct near,the vehicle brake is not enough,the vehicle driver judges the passing height of the limited viaduct wrong,and the vehicle driver does not pay attention when passing the limited viaduct front,etc.Through the structural improvement of the bridge limited viaduct,it can make the limited viaduct have the functions of larger reminder area,collision kinetic energy of the limited viaduct mobile buffer vehicle,movable board to avoid injury,etc.,which can effectively reduce the collision probability between the ultra-high vehicle and the bridge limited viaduct,and avoid the accident of damage to the vehicle and the passenger.
