| 摘 要： | 针对我国高速公路护栏难以满足不同车型碰撞需求的问题,对高速公路护栏的结构及参数进行研究。采用能量守恒方法,建立车辆骑跨护栏事故数学模型,提出了双条半刚性护栏新型结构;采用均匀设计方法,对交通组成要素和车型外形参数进行分析,确定了双条半刚性护栏的有关参数。研究结果表明:该护栏可有效防止微型车下钻护栏和大型、重型车骑跨护栏等恶性交通事故的发生。

| Abstract: | According to the situation that highway guardrail can not meet the crash safety requirements of different vehicles in China,guardrail structure and parameters were studied.By method of energy conservation,vehicle-guardrail saddling model was established and a new double semirigid guardrail structure was presented.Through the method of uniform design,traffic composition and model shape parameters were analyzed,and the parameters of double semi-rigid guardrail was determined.The results show that the new guardrail can prevent the minicar drilling guardrail and large,heavy vehicles saddling guardrail effectively. |

| Keywords: | double-bar semirigid guardrail wave beam guardrail height uniform design optimization design |
