Based on the rapid impact compaction (RIC) technique, the dynamic compaction process of gravel soil ground and dynamic interaction between the concrete bridge foundation and the soil were simulated using the particle flow discrete element method (DEM). The improvement effect and the influence depth of the dynamic compaction of the gravel soil foundation were analyzed based on the porosity variation of the foundation soil during the dynamic compaction process. The influence of the dynamic compaction on the bridge foundation was also analyzed in this study. The feasibility of the numerical simulation for the dynamic compaction process of the gravel soil ground and dynamic interaction of the soil-structure were discussed.
