摘    要:兰渝铁路哈达铺隧道穿越炭质板岩和炭质叶岩,局部还有千枚岩,且围岩走向基本与隧道轴线平行,存在较大的水平应力,施工中出现较大收敛变形,通过介绍哈达铺隧道直立板岩段大变形情况,分析变形的原因,提出了控制措施。

关 键 词:隧道  直立板岩  大变形  控制技术

Large Deformation Analysis of Upright Slate of Hadapu Tunnel and Control Construction Technology
Abstract:The stratum where Hadapu Tunnel of Lanzhou-Chongqing Railway is through is formed with carbonaceous slate and carbonaceous shale,partly phyllite and the surrounding rock is basically parallel to the tunnel axis,with great horizontal stress.Large convergent deformation occurs during construction.Through the introduce of upright slate large deformation of Hadapu Tunnle,the deformation causes are analyzed and control measures are proposed.
Keywords:Tunnel  Upright slate  Large deformation  Control technology
