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.

而钢护栏一般较砼护栏柔一些。

The steel guardrail is generally more flexible than the concrete guardrail.

若需要两者受碰撞后的变形一致，则钢护栏需要更大的刚度。

If it is necessary to have the same deformation after collision, the steel guardrail needs more stiffness.

对钢护栏材料也相应较高。

The material of steel guardrail is also relatively high.
