Abstract

Abstract: The damage mechanism of the wave beam guardrail is analyzed，combining with the investigation on the damaged state of the wave beam guardrail． Maximum deflection of the guardrail beam and the top-offset of the guardrail post are taken as guardrail damaged classification indicators． The index value is derived through mechanical model analysis，and guardrail damaged grade is classified into three levels based on experiment indicators． Finally，the repair program is determined according to the guardrail damaged grade．

Key words: wave beam guardrail, damaged grade, damaged indicators, classification

摘要： 分析了波形梁护栏损坏机理，结合护栏部件的实际损坏情况，以护栏板最大挠度和立柱顶部偏移量作为护栏损坏等级划分指标，根据力学模型分析得出指标值; 以实验验证的指标值为依据，将护栏损坏等级划分为3 个等级;根据护栏损坏等级明确了波形梁护栏的维修方案。

关键词: 波形梁护栏, 损坏等级, 损坏指标, 等级划分
