护栏板是一种吸能结构, 在阻止车辆越出公 路的同时, 还通过变形来吸收碰撞能量, 改变车辆方 向, 较大限度地减少事故损失。 全护栏板是减少交通事故和降低事故恶性程度的有效 措施, 但在不该设置护栏板的地方设置护栏板, 反而成为 新的障碍物, 增加了事故危险。因此, 对护栏板的设计首先要掌握护栏板的特点, 结合高速公路的交通 条件, 在满足护栏板基本功能的前提下, 选用合适的护 栏形式, 并采取合理的设置原则。
Guardrail is an energy absorbing structure and to stop vehicles exceed the public road at the same time, but also through the deformation to absorb the collision energy, change the vehicle to maximize reduce accident losses. Full protecting balustrade is reducing traffic accidents and reduce accident malignant degree of effective measures, but in the setting of rail fence plate is arranged. On the contrary, they become new obstacle, increases the risk of accide波形护栏标准nts. Therefore, the guardrail plate design must first grasp the characteristics of rail, combined with highway traffic conditions, under the premise of satisfying the basic functions of the guardrail plate, selection of suitable protection bar form, and take a rational set of principles.
