受碰撞后的护栏变形程度：受碰撞后护栏的大动态变形量不应超过可允许的变形距离。
Deformation degree of guardrail after collision: the large dynamic deformation of guardrail after collision shall not exceed the allowable deformation distance.
该原则主要是考虑车辆碰撞后是否允许一定的变形。
The principle is mainly to consider whether a certain deformation is allowed after vehicle collision.
例如：桥梁结构物一般都位于地面以上很高处。
For example: bridge structures are generally located very high above the ground.
过大的变形容易导致护栏承受出现除车辆碰撞力以外的其他荷载类型。
Excessive deformation will easily lead to other load types except vehicle collision force.
