P-Y CURVES FOR LATERALLY LOADED PILES DERIVED FROM THREE-DIMENSIONAL FINITE ELEMENT MODEL. NUMERICAL MODELS IN GEOMECHANICS. NUMOG III. PROCEEDINGS OF THE 3RD INTERNATIONAL SYMPOSIUM HELD IN NIAGARA FALLS, CANADA, 8-11 MAY 1989

The design of piles for lateral loads is typically performed using the beam-on-elastic subgrade approach in which the soil response is modeled as a series of discrete nonlinear springs (p-y curves). The p-y curves used in design are based upon empirical rules derived from field experiments. In this study, p-y curves are derived from the bending moments in a pile from a three-dimensional finite element model. A simple elastic-plastic soil model is used as a first attempt at modelling the problem of undrained static loading in clay coils. The results provide insight into the patterns of shear deformation in the soil around the pile and demonstrate the influence of the ground surface upon p-y response. The three-dimensional finite element model is seen to provide a means for investigating effects such as pile-soil-pile interaction in laterally loaded groups, but improved constitutive models for soil and correllations with field experiments are needed.(a) for the covering abstract of this conference see IRRD 824029.
