受碰撞后的护栏变形程度：受碰撞后护栏的大动态变形量。

Deformation degree of guardrail after collision: large dynamic deformation of guardrail after collision.

不应超过可允许的变形距离。

The allowable deformation distance shall not be exceeded.

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.

使受力变得更为复杂。

Make the force more complicated.
