Usual Distinct Element Method (DEM), in which soil is represented as a system of numerous discrete particles, does not account for two factors; the continuity of the medium and wave propagation. The modified method, which is proposed in this paper, has another physical structure which presents the effect of the internal material between particles as pore water or clay. We simulated the two dimensional dynamic fracture of a cliff using this method. The fracture process is as follows; many small cracks occur widely then they form fracture lines. Results confirmed that this method can simulate the continuous and discontinuous medium.
