根据以往施工经验,隧道塌方、坍塌等事故往往是由于不够重视预防围岩变形所造成的,为了保证隧道施工安全,在此根据施工经验将预防控制围岩变形的措施加以分析阐述。
According to the construction experience in the past, accidents such as tunnel collapse and collapse are often caused by insufficient attention to the prevention of surrounding rock deformation. In order to ensure the construction safety of tunnels, the measures to prevent and control the deformation of surrounding rock are analyzed and explained based on the construction experience.
