Abstract：Numerical analysis is made on consolidation mechanism of foundation soil with large deformation hypothesis. Based on collision theory，the concepts of collision coefficient and equivalent collision mass of foundation are proposed. and the dynamic contact condition is also established. Based on energy conservation principle，an energy supplement equation is obtained using optimum model and network parallel computing technology. A dynamic compaction case is taken as an example to analyze with the proposed method. The variation law of foundation displacement with time and the dynamic contact stress under dynamic compaction is obtained，which offers an effective path to analyze consolidation mechanism of soil precisely and also demonstrates the speedup and efficiency of parallel computing.
