The practice of analyzing laterally loaded driven and bored piles often requires modeling of soil response in terms of uncoupled, non-linear unit load transfer functions. These functions, called p-y curves, are input into computer codes that use finite difference or finite element representations of beam behavior. This paper considers three semi-empirical procedures for constructing p-y curves: the soft clay method, the stiff clay method and a new method that intergrates relative pile-soil stiffness and soil degradability effects.
