Small scale model test on lateral behaviors of pile group in loose silica sand

Abstract: The accurate predictions of load- deflection response of the pile group are necessary for a safe and economical design. The behavior of piles under the lateral load embedded in soil, is typically analyzed using the Winkler nonlinear springs method. In this method, the soil-pile interaction is modeled by nonlinear p-y curves in a way that the single pile p-y curve is modified using a p-multiplier (Pm) for each row of piles in the group. The average Pm is called the group reduction factor. The Pm factor depends … Show more

“…Dash et al [7] carried out 12 centrifuge tests to obtain the nonlinear Winkler foundation spring of liquefiable soil. Vakili et al [8] conducted a 1 g model test to obtain the Winkler nonlinear spring of the pile group under the lateral load. Moreover, the nonlinear spring applicable to CFA and Franki piles was proposed [9,10] based on the test method.…”
