架梁山隧道在开挖过程中发生突发性断层塌方,本文针对塌方规模大、涌水量大的特点,通过对注浆加固和开挖方法的动态优化,保证了对塌体安全可靠的处理,其措施可供同类隧道塌方处理参考。
In view of the large scale of landslides and the large amount of water inflow, this paper aims at ensuring the safe and reliable treatment of collapse by dynamic optimization of grouting reinforcement and excavation methods. Its measures for similar tunnel collapse treatment reference.
