摘　　要：公路建设过程中地质灾害时有发生,其中浅埋隧道冒顶较常见。如何有效处理与预防塌方冒顶,是文章研究的重点。为此,文章以广南至那伞高速公路板茂隧道为例,把隧道建设所处的地形地质情况和现实情况相结合,分析冒顶原因,介绍了隧道塌方的预防手段,以在施工过程中提前检测地质,根据实际情况随时调整施工方法。文章旨在为类似隧道已发生的事故处理方法提供参考。Geological disasters occur from time to time in the process of highway construction,with shallow-buried tunnels often experiencing roof fall.How to effectively deal with and prevent collapse and roof fall is the focus of this paper.For this reason,this paper takes Banmao Tunnel on Guangnan-Nasan Expressway as an example,combines the topographic and geological conditions of the tunnel construction with the actual situation,analyzes the causes of roof fall,and introduces the preventive measures for tunnel collapse,so as to detect the geology in advance during the construction process,and adjust the construction method at any time according to the actual situation.The purpose of this paper is to provide reference for the treatment of accidents that have occurred in similar tunnels.
