DEFORMATION MECHANISM OF SLOPE COVERED WITH CLINOSOL AT TUNNEL ENTRANCE AND ASSOCIATED EXCAVATION TECHNOLOGY IN NORTH HUBEI PROVINCE

  • 摘要: 坡积土隧道洞口边、仰坡在开挖后自稳能力差,且受隧道开挖影响,易发生破坏,导致隧道工程无法正常施工,并带来经济损失、危害施工人员安全。本文以香山隧道为工程背景,依据隧址地形地质,建立了隧道洞口边、仰坡的三维仿真模型,结合隧道进洞开挖,分析了洞口边、仰坡的位移和应力变化过程,研究了隧道开挖对边、仰坡的影响,优化了隧道进洞方案。研究结果表明,边、仰坡开挖坡度与原始坡度突变处会产生应力集中并形成贯通的潜在滑移面,隧道开挖对仰坡变形影响较大,坡形坡度对隧道洞口边、仰坡稳定性具有显著影响,放缓坡度和采用分步台阶开挖可有效改善边坡应力应变状态。
