| Abstract: | According to the quiddity of dynamic design, the 3D-σ is applied on the typical cross section of tunnel selected from an actual twin-arch tunnel case to set up the three-dimensional tunnel mechanics model. The 3D-σ model and different support parameters are used to simulate and analyze the stress and displacement in the wall rock mass during shotcrete-rock bolt support. It not only offers the theoretical foundation for the adjusting and simplifying of the construction procedure, but also has made good social economic benefits. |
