桥梁隔离防撞栏 茂名不锈钢复合管灯光护栏
Bridge isolation anti-collision barrier Maoming stainless steel composite tube light barrier
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.
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 more flexible than the concrete guardrail, and the deformation of the two guardrails after collision is consistent if necessary.
则钢护栏需要更大的刚度，对钢护栏材料也相应较高。
Therefore, the steel guardrail needs more stiffness, and the material of steel guardrail is also relatively high.
