摘　　要：近些年来,隧道冒顶塌方时有发生,不仅造成经济损失,还严重威胁到工人的生命安全,因此预防和处理塌方变得尤为重要。结合王主山隧道冒顶塌方实例,分析事故产生原因,结合实际采取了洞外止水覆盖、洞内反压回填、超前加固等处置措施,有效解决了隧道冒顶塌方的问题,并提出了预防措施。In recent years,the collapse of tunnels has occurred,not only causing economic losses,but also seriously threatening the safety of workers.Therefore,it is particularly important to prevent and deal with landslides.Based on the example of the collapse of the Wangzhushan tunnel,this paper analyzes the cause of the accident,and takes measures such as sealing outside the water,backfilling in the cave,and pre-reinforcement,which effectively solves the problem of collapse of the tunnel and proposes preventive measures.

关 键 词：冒顶塌方 止水覆盖 反压回填 超前加固
