Basing on the tunneling of Jiaowu tunnel, combining with finite element program, the continuous excavation by load steps is simulated through the “activation and passivity” method. The mechanics behavior of the half-open and half-hidden structure tunnel and the characteristic of stress and deformation of surrounding rock supporting system are studied and gained. By comparing the analysis results with in-situ testing data, Analysis shows that the calculation is correct and that tunneling surrounding rock deformation is of predictability.
