摘要
针对软弱围岩隧道跨度大、埋深浅、地质情况复杂、施工环境要求高等特点,对此类隧道的施工控制关键因素进行了探讨,提出了新奥法施工的主要开挖方法,为软弱围岩隧道施工积累了经验。
This article discusses about key factors of construction control in tunnel with soft surrounding rock since such kind of tunnel has large span, shallow embedded depth, complex geology situation high requirement on constructional environment. It proposes excavated method New Austrian method, accumulates experience for construction in tunnel with soft surrounding rock.
