照壁山隧道出口碎屑流地层围岩加固处理技术

On surrounding rock consolidation technique for debris flow layer at Zhaobi Mountain's tunnel exit

结合工程实践,介绍了在照壁山隧道施工中遇到碎屑流地层时对围岩的加固处理技术,通过后期施工实践证明采取的加固措施取得了很好的效果,为同类工程施工提供了参考。

Combining with the engineering practice, the paper introduces the consolidation technique for the surrounding rock in the tunnel con struction of Zhaobi Mountain, proves the consolidation measure has better effect by the construction practice at later period, so as to provide some reference for similar projects.
