| 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. |
