A damage model that can reflect characteristics of impact load and anisotropic damage evolution has been embedded into FEM software; and the damage characteristics of cement mortar block with prefab cracks under blasting have been simulated. The results of research indicate that a serious damage zone exists nearby blasting hole. The range of the serious damage zone can be determined by the simulating results. The simulating results are similar to the one from test. So
the method proposed can provide theoretical evidences for stability analysis of rock that has been disturbed by blast loading in geotechnical engineering.
