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，使受力变得更为复杂。
Too large deformation will easily lead to the occurrence of other load types except vehicle collision force, which makes the stress more complex.
而钢护栏一般较砼护栏柔一些，若需要两者受碰撞后的变形一致。
The steel guardrail is generally softer than the concrete guardrail. If it is necessary, the deformation of the two guardrails will be the same after collision.
则钢护栏需要更大的刚度，对钢护栏材料也相应较高。
The steel guardrail needs more rigidity, and the steel guardrail material is also relatively high.
