摘要
在进行强夯加固处理松软的粗粒巨粒地基土的过程中,任何夯点有效受力范围内的土体压缩加密都受三个阶段的控制,即孔隙缩小阶段、颗粒形变阶段(颗粒挤密阶段)和颗粒镶嵌阶段。然而夯锤底面积控制的垂向土体呈逆向转换的现象。因此,建立了夯点土体形变模型和夯后检验模型。
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.
