| Abstract: | A model for simulating and analyzing a dynamic consolidation procedure is presented in this paper. Based on the governing equations for analyzing 3-dimensional fluid-solid coupled problems in porous media,a variational principle and the corresponding finite element method are proposed. Procedure of single-point and single-time ramming is simulated by using the finite element method for axisymmetric problems. The solution method is introduced in detail. Finally,a sample problem is provided and the computational results then obtained are compared with the data measured in a construction site. |
