✦ Synopsis

Two-dimensional "nite element analysis has been used to "nd load}transfer relationships for translation of an in"nitely long pile through undrained soil for a variety of soil-constitutive models. It has been shown that these load}transfer curves can be used as p}y curves in the analysis of single piles undergoing lateral pile head loading in undrained soils with non-linear stress}strain laws. Lateral pile response deduced from 2-D analysis input to the subgrade reaction method has been compared to the behaviour of a single pile analysed using three-dimensional "nite element analysis. Good agreement between the two methods for non-linear soils suggests that the 2-D analysis may form a useful design method for calculation of p}y curves.
