小间距隧道施工应急处理探讨

摘要

结合卧龙沟2号隧道的施工情况，详细阐述了小间距、浅埋、偏压隧道重点难点控制性工程的应急处理措施，总结了左洞初支偏压形变、中夹岩应变、后行洞初支形变等处理关键技术，以确保隧道施工的安全性。%Combining with Wolonggou No. 2 tunnel construction conditions, the paper specifically describes emergent treatment measures of small-spacing, shallow-burying and biasing tunnel control engineering, and summarizes critical treatment techniques, such as preliminary left tunnel bi-asing deformation, central rock strain, post tunnel support deformation and so on, with a view to ensure tunnel construction safety.
