| 英文摘要 | The weak formulation of the Lagrangian control equations considering the contact constraint conditions and the FEM discrete equations have been derived. The non-linear and non-smooth problems of the mechanical response are solved perfectly by adopting the suggestion method for which tolerance large tangential slipping of the contact surface. One excavation bedding rock slope of the Hu-Rong-Xi expressway is analyzed applying the method mentioned above. The distribution rules of the displacement, stress, strain, contact state, contact friction force and sliding distance under the status of critical sliding are obtained. The analysis results indicate that the failure of the bedding slope is a progressive course. The interlayer stagger firstly, then the deformation evaluates to creep bedding slip and the bottom rock occurs buckling slip at last. The destruction model changes form the bedding slide to rock buckling slip. |
