摘要
以岳家岭隧道YK26+587处塌方为例,分析影响隧道开挖的工程地质条件、地下水对隧道主体结构的不利影响、地表注浆加固岩体的处理与施工。详细阐述了隧道进出口浅埋段施工应注意的事项及塌方后相应的处理措施。
In light of the landslide in YK26 ＋ 587 of Yuejialing Tunnel,this paper analyzes the geological conditions affecting tunneling,underground water＇ s adverse influence on tunnel main structure,treatment and construction of surface grouting for reinforcing rock bodies.Things needing attention in shallow-buried section construction of tunnel openings and measures for treating landslide are detailed as well.
