| 摘 要： | 针对国内某高速中央分隔带护栏升级改造问题，提出了中央隔离带组合式护栏方案，建立了组合式护栏的三维汽车—护栏碰撞仿真模型，并针对不同的护栏立柱间距进行了汽车碰撞仿真模拟研究。结果表明，利用中央隔离带旧护栏改造为组合式护栏满足规范要求，可以有效地降低成本，为高速公路中央分隔带护栏改造提供依据。 |
| 关 键 词： | 组合式护栏 护栏立柱间距 碰撞仿真 |

| Abstract: | For the problem that the upgrade issue of domestic high-speed central median guardrail, a new double-beams highway guardrails was proposed. The 3D collision model of guardrail and vehicle was created, and the collisions in different column？spacing are simulated. The results indicated that the new double-beams highway guardrail which has lower cost and barrier recycle meets regulatory requirements. It provides the basis for reconstruction on China＆#39;s central highway and can be applied in our country’ s expressway barrier reconstruct. |
