ABSTRACT: Piles might be subjected to passive loading from permanent ground deformations. The present study investigates the lateral force on a pile resulting from a downslope displacement of a clay crust over a liquefied soil layer. Finite-element (FE) analyses are performed to calculate the total force and its variation with depth in the segment of the pile in the crust. Analyses are performed for a single row of piles with a varying centre-to-centre spacing and undrained shear strength of clay. The FE results show that the pile behaves as a single pile when the spacing is greater than five times its diameter. The arching effects in relation to pile spacing are discussed. The lateral force per pile decreases with a decrease in pile spacing. Using the calculated maximum lateral force, a separate analysis is performed to examine the structural response of a long pile installed through the liquefied layer on a stable soil layer.
