摘要
隧道软弱围岩段开挖施工是隧道工程难点,直接影响隧道施工的质量、安全与进度。本文结合刘家隧道软弱围岩段实体工程,分析了软弱围岩对隧道开挖施工的不利因素,详细阐述了隧道软弱围岩段开挖施工的处治方法,为解决隧道软弱围岩段开挖施工提供参考。
Tunnel excavation in weak surrounding-rock is a difficult point in tunnel engineering,which directly affects the quality,safety,and progress of tunnel construction.Taking the solid engineering of the weak surrounding-rock section of Liujia tunnel as example,this paper analyzed in detail the unfavorable effects of the weak surrounding rock to the excavation construction of the tunnel and expounded the treatment methods for the excavation construction of the weak surrounding-rock section of the tunnel,which provided reference for the excavation construction of the weak surrounding-rock section of the tunnel.
