| 中文摘要: |
| 以大梁峁特长公路隧道为依托，针对水平层状岩体隧道，采用ANSYS数值分析软件将水平泥岩砂岩互层岩体等效为正交各向异性的方式，对隧道开挖过程中围岩稳定性进行了数值试验分析，通过分析围岩塑性区、围岩应力、隧道变形、锚杆轴力、初支及二衬内力，得出施工采用支护参数的合理性和水平泥岩砂岩互层隧道围岩变形和初支、二衬应力的分布特征。 |
| 英文摘要: |
| Based on the horizontally bedded surrounding rock of the Da Liangmao extra long highway tunnel, the stability of surrounding rock has been studied by the numerical simulation. The horizontally mudstone and sandstone inter layered rock mass is equivalent to the orthogonal anisotropic material in ANSYS. Through the analysis of the surrounding rock plastic zone, surrounding rock stress , tunnel deformation, the inner force of anchor and internal force of lining, the rationality of the support parameter and the distribution characteristics of the tunnel deformation and internal force of lining are studied. |
