CFI's Driven Pile Academy: Hosted by the PDCA

Soil Set-up

Increase of soil resistance with time Disturbed soil remolds around pile Pore water pressure dissipates and effective stress of soil against pile increases over time Occurs to some degree in almost all soil conditions but generally: ◦ Cohesionless Soils (sands): to a lesser degree but setup is almost immediate ◦ Cohesive Soils (clays): may increase by a factor of 10X from initial installation but takes longer
