Abstract
Vibro replacement stone columns were installed for soil improvement for the construction of a 20,000-square-foot operational storage facility in Coronado, CA. The soil improvement program was conducted to meet seismic and static performance criteria for spread footings founded on improved soil. CPT testing was conducted before and after stone column construction to verify the vibro replacement program. Comparison between pre- and post-construction CPTs showed remarkable increase in the tip resistance in loose sand layers. Accounting for densification and shear reinforcement, the anticipated post-improvement liquefaction-induced settlement was reduced significantly.
