| Abstract: | In this paper, the procedure of single-point and multiple-time ramming for loess is simulated using the finite element method.The graph about the distribution of stress, displacement and pressure in the foundation during dynamic consolidation are provided in a sample with Han-chang expressway as an engineering background.The computational results obtained are compared with the data measured in the consolidation site.An effective path to simulate the consolidation mechanism precisely is provided. |
