| 英文摘要 | Abstract In order to analyze the influence of different excavation methods on the stability of the tunnel, with reference to a tunnel engineering case, a three-dimensional finite element software was used for numerical simulation to study the stress variation, deformation and plastic zone distribution of surrounding rock during the excavation of the double arch tunnel under two different excavation methods, CD method and benching method. The results show that for the CD method, when the distance between left and right tunnel faces is more than 60m, the deformation, stress and plastic zone of surrounding rock and supporting structure tend to be stable. For the benching method excavation, when the distance between the left and right tunnel faces is more than 50m, the deformation, stress and plastic zone changes of surrounding rock and supporting structure tend to be stable. |
