摘要
介绍了公路隧道沿线穿越多种不良地层,隧址区地层物理力学性质的相关情况,并针对岩爆、软弱围岩塌方、涌水、溶洞、软弱围岩大变形等提出了相应的对策措施。
This paper introduced the circumstances related to the physical and mechanical properties of stratum in the tunnel site for the highway tunnel traversing various kinds of unfavorable stratums along the line.The corresponding counter measures were proposed based on rock burst, weak surrounding rock collapse, water gushing and large deformation of weak surrounding rock.
