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。

关键词: 双条半刚性护栏, 波形护栏, 高度, 均匀设计, 优化设计

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.

Key words: double-bar semirigid guardrail, wave beam guardrail, height, uniform design, optimization design
