In the study a 2 dimensional model test was executed to grasp the effect of the taking load of equipments on the ground when improving a soft ground like dredging reclaimed ground. The static load and the dynamic load in the consolidated model ground was $0.02kg/cm^2,;0.03kg/cm^2;and;0.04kg/cm^2$ respectively. After consolidating far two months by consolidation load of $0.02kg/cm^2,;0.03kg/cm^2;and;0.04kg/cm^2$ respectively, the ultimate bearing capacity was $0.16kg/cm^2,;0.19kg/cm^2,;0.24kg/cm^2$ respectively. And the energy price of dynamic load test at the same point as the settlement of static load test indicated $E=336{sim}945kg{cdot}cm,;E=252{sim}780kg{cdot}cm;and;E=323{sim}727kg{cdot}cm$ for each consolidation load. When the static load and the dynamic load operated at the same ground condition, the heaving quantity was bigger in the case of the dynamic load than in the case of the static load, and the horizontal displacement quantity the in the case of dynamic load was exhibited very deficiently compared to the quantity in the case of static load test.
