摘　　要：文章从山区高速公路隧道塌方研究现状入手,从多个方面分析了造成隧道塌方的原因,重点介绍洞顶地表处理和洞内加固法的应用。该法针对围岩地质条件复杂、洞顶覆盖层厚度较薄的隧道塌方,具有操作方便、经济安全等优点,可为同类隧道塌方处理提供借鉴参考。Based on the research status of expressway tunnel collapse in mountainous areas,this paper analyzes the causes of tunnel collapse from many aspects,and focuses on the application of tunnel top surface treatment and in-tunnel reinforcement method.This method has the advantages of convenient operation,economy and safety for tunnel collapse with complex geological conditions of surrounding rock and thin overburden on the top of tunnel,which can provide reference for similar tunnel collapse treatment.
