Ground improvement using rapid impact compaction: case study in Dubai

Abstract

In recent years, the Rapid Impact Compaction has gained popularity as a ground improvement technique. To evaluate the usefulness of this technique in the Arabian Gulf Region, the RIC is used to improve an area of 29,000 m2 on a project site near Dubai, UAE, where the groundwater level is shallow. Cone Penetration Tests and settlement calculations were carried out before and after soil improvement. Test results show improvement in the soil bearing capacity and reduction in expected settlements.
