An extensive laboratory testing program was conducted on model spread foundations to investigate the influence of backfill density state, native soil density state, foundation depth, and foundation shape on the uplift capacity and load-displacement response of spread footings in cohesionless soils. The results reinforce earlier EPRI studies on foundation capacity (EL-2870) and load-displacement response (EL-6965). The current study demonstrates the great importance of compaction on both capacity and load-displacement response, with the effects being greater for denser native soils. The results include an improved overall design approach for uplift-resisting spread foundations.
