海龙屯龙虎大道危岩体稳定性分析及加固工程研究

以贵州省遵义市海龙屯龙虎大道存在危岩体的典型泥灰岩、白云岩互层岩层边坡中的W3及W4危岩体为例，通过极限平衡计算和FLAC3D数值模拟分析，直观地展现了其变形破坏模式。结果表明:W3及W4危岩体均处于欠稳定状态，变形最大处在崖面附近。由此分析结果，提出加固方案为裂隙注浆+悬臂梁衬砌+锚杆复合加固。

Stability Analysis and Reinforcement Works Study of Dangerous Rock Mass along Longhu Avenue,Hailongtun Village

There exists dangerous rock mass in the typical marlstone and dolostone interbedding slope along Longhu Ave., Hailongtun Village, Zunyi City, Guizhou Province. Herein Dangerous Rock Mass W3 and W4 were taken as the examples to make limit equilibrium calculation and FLAC3D numerical simulation, by which the deformation failure mode of the rock was exhibited directly. The research shows that Dangerous Rock Mass W3 and W4 are understable both with the maximum deformation close to the cliff face. Based on this result, the reinforcement scheme was proposed as follows, crack grouting+cantileverbeam lining+composite reinforcement of bolt.
