| Abstract: | The sigle-point ramming process of loess road foundation was simulated by the finite element method. The distributions of stress, displacement and pressure in the foundation during dynamic consolidation were provided with a sample of Han-Chang Expressway. Computational results were compared with the measured data at the consolidation site. It is shown that the numerical simulation can exactly reveal the change of physical and mechanical parameters of the collapsible loess foundation during dynamic consolidation. |
| Keywords: | dynamic consolidation collapsible loess numerical modeling |
