摘要
在软弱围岩隧道施工中 ,遇到的最大问题是围岩自稳能力差和水对围岩的破坏 ,本文阐述了用深孔注浆超前加固地层 ,提高围岩自稳能力和消除水隐患的施工技术 ,对软弱围岩隧道施工有较强的针对性。
In the construction of tunnels with soft surrounding r ocks,the most difficult problem encountered is the poor stability of the rocks a nd the damage of the surrounding rocks by water.This paper describes the technol ogy of enforcing the stability of the rocks and removing the potential water dam age by applying deep boring grouting method to achieve the pilot consolidation o f the rocks.It is well aimed at the construction of tunnels with soft surroundin g rocks.
