    Research on Stability and Excavation Types of Shawan Tunnel

      Graphical Abstract
      • Abstract
    • From the analysis of Shawan underground tunnel model,we take the cross section of IV surrounding rock as an example to calculate the displacement and stress of surrounding rock,lining and the stress of anchor bolts,then to research the influences of various excavation types of the tunnel surrounding rock’s stability.Finally,we optimize the support and excavation of tunnel and prove the rationality of the design.
