摘　　要：结合经典岩体力学理论分析了隧道围岩失稳的原因,然后提出了基于Hoek-Brown强度准则的围岩稳定分析方法,并且结合工程实例论述了其在隧道围岩分析中运用的优越性,认为用其判别完整坚硬围岩的破裂扩展情况的方法是可行的。Combining with classical rock mass mechanics, the essay analyzes causes of tunnel surrounding rock instability, and shows surrounding rock stability analysis method based on Hoek-Brown strength criterion. Integrating with the engineering cases, it discusses its priority in tunnel surrounding rock analysis, and holds that the method of using Hoek-Brown strength criterion to tell the extension fracture of complete and hard surrounding rock is feasible.
