摘　　要：结合大跨度浅埋隧道衬砌的受力情况比较复杂的特点,通过对广乐高速公路某隧道的二次衬砌结构进行静力分析,验证了设计采用的二次衬砌厚度和配筋率是合理可行的,可为同类大跨度浅埋隧道的二次衬砌结构设计提供参考。Combining with the characteristics of complex stress situation of large span shallow buried tunnel lining, through the static analysis on secondary lining structure of a tunnel in Guangle highway, verified the thickness and reinforcement of secondary lining was reasonable used in de- sign, could provide reference for similar secondary lining structure design of large span shallow buried tunnel.

关 键 词：大跨度 浅埋隧道 二次衬砌 静力分析
