公路隧道衬砌结构火灾损伤检测与评价

文章通过对公路隧道衬砌结构的火灾损害机理分析,用超声波法对隧道衬砌结构火灾损伤检测,对隧道衬砌在火灾中受火时间、衬砌的损伤层厚度及衬砌结损伤的力学性能及强度进行评价,针对隧道衬砌耐火性能提出隧道结构设计与施工的注意要点,为今后的隧道衬砌结构的防火设计提供参考。

Detection and Evaluation on Structure of Highway Tunnel Lining Damage in Fire

In this paper,based on the research on the fire damage mechanism of highway tunnel lining structure,the detection of injury is done by ultrasonic method after fire,makes envaluation on fire duration,damage layer thickness and performance of mechanics and strength of highway tunnel lining and puts forward some effective methods and measures that can be used to improve the fire-resistant property of the structure of highway tunnel lining,and provides the reference for the design of the futural fire-resistant of highway tunnel lining.
