受碰撞后的護欄變形程度:受碰撞后護欄的大動態(tài)變形量。
Deformation degree of guardrail after collision: large dynamic deformation of guardrail after collision.
不應超過可允許的變形距離。
The allowable deformation distance shall not be exceeded.
該原則主要是考慮車輛碰撞后是否允許一定的變形。
The principle is mainly to consider whether a certain deformation is allowed after vehicle collision.
例如:橋梁結構物一般都位于地面以上很高處。
For example: bridge structures are generally located very high above the ground.
