以山西云中山隧道工程为依托,针对花岗岩隧道,当软弱夹层相对隧道的位置不同时,在工地现场监控量测的基础上,采用数值模拟方法和现场监控量测进行对比,并运用有限元方法,对软弱夹层在角度、长度和宽度特定、而相对于隧道的位置不同时的几种情况进行了数值模拟,具体分析了支护结构的弯矩以及锚杆受到的轴力等变化规律,并把模拟分析得到的结果和监测的结果进行了对比分析,揭示了软弱夹层对隧道围岩稳定性的影响规律,最后提出了采用这种方法的注意事项。

Taking Yunzhongshan tunnel engineering in Shanxi province as the background,in light of granite tunnel,based on in-situ monitoring and measurement,the essay makes a comparison by using numerical simulation method and in-situ monitoring and measurement when the location of weak intercalated layer is different according to the location of tunnel.Applying finite element method,it carries out numerical simulation of several conditions when the angle,length,and width of weak intercalated layer are fixed and the location is different according to the location of tunnel.And then,it specifically analyzes the changing law of bending moment of bracing structure and axial force of anchor pile,compares and analyzes simulation results and monitoring data,and demonstrates the influential law of weak intercalated layer on the stability of tunnel surrounding rock.In the end,it puts forward matters needing attention of this method.
