高速公路护栏碰撞过程分析与力学模型

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.
