摘　　要：公路隧道穿越软弱破碎围岩需控制地表沉降与围岩变形,保证施工合理性,方能提高工程质量。文章以某公路隧道工程为例,简要阐述了软弱破碎围岩特性,提出超前地质预报预测技术、管棚超前支护技术、三台阶法开挖技术、注浆堵水技术的综合施工方案,并采取恰当监测技术验证隧道施工效果,以期为相关工作者提供参考。When a highway tunnel passes through weak and fractured surrounding rock,it is necessary to control surface settlement and rock deformation to ensure construction rationality and improve engineering quality.The article takes a highway tunnel project as an example to briefly explain the characteristics of weak and fractured surrounding rock,and proposes a comprehensive construction plan including advanced geological prediction technology,advanced support technology for pipe sheds,three step excavation technology,and grouting and water blocking technology.Appropriate monitoring technology is adopted to verify the tunnel construction effect,in order to provide reference for relevant workers.
