Abstract
In order to study the character of cross-fault mountain tunnel under reversed-slip fault dislocation, the inter-action model between the rock and the tunnel is made on the basis of the principle of the finite element and the pseudo-static method. The method for analyzing the nonlinear responses of the cross-fault tunnel under load of fault dislocation is also developed. The analysis is performed by using the displacement function of finite element soft-ware. The effect of fault dislocation is simulated by imposing displacement load on the hanging wall rock. The values of displacement load are imposed by 100 steps to describe the loading process. With the increase of fault dislocation the stress states of the tunnel under the condition of reversed fault are analyzed. By the computation, some meaningful results have been obtained, such as when the tunnel is under a safe state, which part is easy to damage and how the damage occurs.
