Settlement Prediction Using the Settlement Velocity in Dredged and Reclaimed Clay Ground

When improving soft ground, the settlement measurement results are used to evaluate the final settlement and consolidation using the existing settlement analysis method to determine whether or not to improve the ground. However, the long-term consolidation settlement exceeds the allowable settlement at the site dredged and filled with clay in the Busan New Port area. This happens frequently. In this study, the results were compared and analyzed using a conventional analysis method and a new analysis method using the settlement velocity using measurement results from a site dredged and filled with clay. As a result of the study, the analysis method using the settlement velocity was better than the conventional method. The accuracy was found to be high, confirming that it is a practical analysis method.
