Presentation
Our next Southbay Engineers Club meeting is an educational program on Deep Dynamic Compaction (DDC), a ground improvement process that utilizes 10 to 30 ton weights (tampers) dropped several times by a crane between 50 to 100 feet high. DDC is performed in a pattern over a site to densify the subsurface soils, typically 20 to 30 feet deep. DDC is used to improve subsurface soils such as landfills, deep undocumented fill, and for liquefaction remediation. Our speaker will describe two unique DDC test programs that were performed at two sites to determine the effectiveness of DDC ground improvement for liquefaction mitigation.
