高速公路护栏碰撞分析与力学模型

Analysis of Freeway Guardrail Collision and Mechanical Model

从高速公路交通事故的统计资料出发,分析了汽车与高速公路护栏碰撞事故在交通事故中的比例及发展趋势,提出护栏碰撞研究。对护栏碰撞进行仪器、过程方面的介绍,并进行了力学分析,总结分析结果,提出了改善高速公路交通安全的措施,指出了本领域的研究展望。

Starting form the statistic data of highway traffic accidents, the car-barrier impact accidents on highway were investigated with its proportion and trend indevelop-ment among domestic and abroad traffic accidents, and this paper proposes guardrail collision study, introduces the process and instrument of highway guardrail collision, give mechanical analysis,and summarize the results of analysis. The research prospects in this field are also proposed.
