| Abstract: | In this paper, discontinuous deformation analysis method with four-node element was dynamically studied in surrounding rock around excavation. The results show that the method especially applies to jointed rock masses subjected to large displacement, large deformation and dynamic situation. It is completely discontinuous dynamic analysis method. |
