摘要
以某隧道在Ⅳ级围岩条件下仰拱开挖过程中,拱脚开挖长度过大而导致隧道失稳塌方为例,通过数值分析隧道仰拱塌方失稳机理,指出了当前隧道仰拱施工中应注意的安全事项,可为隧道设计和施工安全控制管理者提供参考。
Taking the tunnel instability collapse owning to extra-long arch springing in the tunnel invert construction under grade IV surrounding ock condition as an example, the paper carries out numerical analysis of the tunnel invert collapse instability mechanism, and points out tunnel nvert construction matters, which will provide some guidance for tunnel design and construction safety control managers.
