Liquefaction of saturated loose granular sand and non-plastic silty sand deposits during seismic loading has caused significant damage to structures and highway systems in almost all major earthquakes. Sand deposits densified by dynamic compaction (DC) are more resistant to liquefaction, and have performed well during earthquakes. Silty sand deposits appear to densify and. perform well when improved by DC supplemented with wick drains. The current practice for evaluating feasibility and choosing the operational parameters of the DC technique at a site depends mainly on field trials, past. experience at. similar sites, and empirical equations based on reported records.
