摘要
主要介绍了某隧道在进出口围岩较破碎的情况下,在施工中采用长管棚及注浆的施工方法,有效地阻止了开挖时软弱围岩的坍塌和涌水,为隧道的施工安全提供了保障,可供同类工程借鉴。
This paper mainly introduces the con- structive method used in fractured surrounding rock at one tunnel construction. During the construction, long-pipe shed and injection grouting methods can effectively prevent the collapse of weak surrounding rock and water inflow in the excavation, and guarantees the safety of construction. It can be referred by similar engineering.
