摘要
崩塌松散围岩隧道施工中常遇到山体整体稳定和掌子面塌方等技术难题,结合桑州岭隧道工程,对浅埋隧道的锚杆加固进行理论分析,对隧道开挖过程中山体稳定进行监控,并对掌子面塌方进行了成功预报,指出松散围岩中蓄水层对掌子面稳定的影响,所得结论对崩塌松散围岩的施工有较好的指导意义。
This paper deals with stability of the Sangzhouling Tunnel construction. First, FEM is used to analyze the stability of the shallow tunnel section, and soil nails are used to improve the upper soils. Second, monitoring work is done deliberately. The collapse of local face is predictsed successfully. The monitoring results show the influence of the aguifers in the loose surrounding rock on the stability.
