Abstract

Dynamic compaction is a widely used ground improvement method applicable to a variety of soils including collapsible loess. The paper presents site characterization and ground improvement performance results obtained from a 22 kilometer motorway project in Constanta, Romania. High energy dynamic compaction was utilized to treat 240.000 square meters of ground to depths ranging from 6 to 8
meters in order to reduce settlements and mitigate collapse potential. The field results are compared to the results of a finite difference numerical model, developed to simulate the dynamic compaction.
