高速公路护栏端部处置对策研究

Research on the disposal of the end of the highway guardrail

护栏端部若处理不当可能会引发严重的交通事故,为降低护栏端部事故严重度,减少人员伤亡和财产损失,文章根据国内护栏端部处置现状,提出护栏不同位置的端部处置对策。经实车足尺碰撞试验验证,各项指标均能满足评价标准的要求,在实际工程中应用,将增强护栏的整体防护效果。

If the guardrail ends are improperly handled,serious traffic accidents may be caused. In order to reduce the seriousness of the guardrail end accidents and reduce the casualties and property losses,the article puts forward the countermeasures of the end treatment of the guardrail in different positions according to the status of domestic guardrail end disposal. The results are verified by full- scale real vehicle crash test,the indicators meet the requirements of the evaluation criteria,and in practical engineering applications the overall protection effect of guardrail would be enhanced.
