| Abstract: | The computing program of DDA is expanded and developed based on DDA computation model in this paper. Large displacements of slope and surface deformation due to underground excavation are discussed using the DDA model with results compared with those from DEM. It is shown that the results are in accordance with those of DEM. All of the analysis proves that DDA can be effectively applied to large rock engineering. |
