摘　　要：在隧道施工中,洞口浅埋段往往因岩石风化严重,且地表覆盖松散堆积层,是塌方等地质灾害的高发区段。以承秦高速公路承德段岔沟门隧道塌方为例,分析洞口浅埋段隧道塌方发生的主要原因,提出处理方案,并对今后预防该类塌方提供建议。Shallow-buried entrance zone is always the position where collapse occurs frequently in tunne-ling because rock always weathers deeply and quaternary loose layer always deposits there.Taking the collapse in Chagoumen tunnel at Chengde-Qinhuangdao Expressway as an example,main reasons of collapse at shallow-buried tunnel are analyzed,its treatment method is provided and suggestion of prevention for collapse in shallow-buried tunnel is given.

关 键 词：承秦高速公路 浅埋隧道 塌方
