Preloading consolidation with drains (PCD) and dynamic compaction (DC) are often combined to improve the ground condition. A novel method of modeling PCD and DC in centrifuge is developed in this study. 3D printing technique is used to greatly improve the manufacturing precision and simulation ability of sand drains. A loading container, which allows adding sand in it stage by stage, is well designed...
The dynamic compaction (DC) method is an effective ground treatment technique that is widely used for a variety of soil types and conditions, particularly in loess areas. However, DC is rarely applied to ground where thick collapsible loess is present. The conventional DC method exerts an energy level of no more than 5000kN·m. Although the DC for collapsible loess treatment is increasing, the use...
