Abstract: Nonlinear FEM based on explicit time integration is applied to simulating the collision process of dynamic compaction. Many characters are taken into account, such as material nonlinearity, geometric nonlinearity, contact nonlinearity, movement nonlinearity and coupling characters of them, etc. The variation processes of collision force of hammer and deformation and stress of soil have been obtained at different heights, weights and areas of hammer. The analysis results indicate that the displacement of soil lags behind the stress of soil. The collision's entire process of hammer and soil and the common phenomenon in the dynamic compaction’s process has been reappeared.

Key words: dynamic compaction, finite element method, large deformation, dynamic contact
