Some numerical experiments with a three dimensional finite element model of a laterally loaded pile
Abstract This paper describes the results of several numerical experiments performed with a three dimensional finite element model of a laterally loaded pile. The experiments are used to investigate the effect of several factors on the p-y curves derived from the model. The three dimensional finite element model utilizes a plasticity model for soil with interface elements which allow gap formation; the model has been described by Brown and Shie (1). P-y curves are widely used in design because of the relative simplicity of the beam on elastic foundation approach and the ability of design p-y curves to represent nonlinear soil behavior. However, it is recognized that this procedure does not represent the soil as a continuum and that the relative importance of some possibly significant factors may be obscured. The procedures used to develop p-y curves are largely empirical. P-y curves derived from the three dimensional finite element model are used in this study to investigate the effect on the soil response of pilehead fixity, in-situ soil stresses, pile/soil interface friction, and sloping ground. The results provide the type of information needed to intelligently utilize the p-y method in the design process.
