摘要:
以明垭子软岩隧道为工程依托,结合现场围岩岩性应用理论分析得出隧道围岩变形的理论极限位移,通过FLAC数值模拟软件建立相应的计算模型,分析了现场施工引起的隧道围岩变形值,根据位移评判依据来评判隧道的稳定性,通过现场监测分析明垭子隧道围岩的变形特点。研究结论对软岩隧道的安全施工有一定的参考价值。
Abstract:
The surrouding rock stability of soft rock tunnel is a difficult issue in the engineering. Taking Mingyazi tunnel of Shitian highway as an example,combined with the scene surrounding rock, applied theory to draw the ultumate displacement of tunnel surrounding rock deformation.FLAC numerical simulation software is used to create a calculation model.Tunnel surrounding rock deformation is analyzed.According to judgment basis of the displacement to judge the tunnel stability. Analysising the deformation characteristics of Mingyazi tunnel through on-site monitoring.The evaluation method has a certain reference value for the safety of the soft rock tunnel construction.
