Abstract
The dynamic drainage consolidation (DDC) method is a relatively new technology for soft soil improvement. The method was adopted for the improvement of the mud at a site for the construction of a highway. The in-situ monitoring on the porewater pressures and settlements of the mud were taken for understanding its field dynamic properties. The site original data on the mechanical responses of the mud under dynamic loading were obtained and analyzed. The some important phenomena on pore water pressures were observed. The settlements induced by dynamic tamping and soil fill were also observed. Some basic mechanisms on the behavior of the soft soil under the dynamic loading are discussed. Effect assessment on the improvement is also taken. The in-situ monitoring and analyses show that the dynamic drainage consolidation is more effective than traditional dynamic consolidation in the improvement depth and consolidation rate as well as the application range; the drainage system play an important role.
