| Abstract: |
| In the course of dynamic compaction reinforcement and treating floppy foundation,earth volume is compressed in the effective scope of getting force to any tamping point,which is controlled by three stages that is reducible porosity stage,granules deformation stage(granules compaction stages) and granules inlaid stage.However,A reverse change phenomenon appear under tamping hammer's bottom area control in the vertical direction of earth volume.Therefore,tamping point earth volume deformative model and test model after dynamic compaction are researched. |
