摘要
以浏阳河隧道典型段为例,利用拱顶下沉值和隧道周边收敛监测结果,研究和分析变形机理,改变开挖方法和加固方法等施工工艺,可为类似特大断面Ⅳ、Ⅴ级围岩隧道施工提供参考和评价依据。
Taking the Liuyang crossing River Tunnel as an example, using the vault sinking and surrounding convergence monitoring results, research and analysis deformation mechanism, improving the excavation and reinforcement construction methods, providing reference and basis for similar super section Ⅳ,Ⅴ- Rock tunnel construction.
