摘要
基于公路隧道工程开挖施工中的超欠挖问题,从工程地质条件、开挖技术方式2方面分析超欠挖控制的影响因素,并从不同的角度入手,探究公路隧道开挖中超欠挖的具体控制方式。
Based on the problem of overbreak and underbreak in highway tunnel excavation,the influencing factors of overbreak and underbreak control are analyzed from two aspects of engineering geological conditions and excavation technology.Finally,the specific control methods of overbreak and underbreak in highway tunnel excavation are explored from different angles.
