Strain wedge (SW) model analysis has been used to evaluate the response of a single pile or group of piles (including its pile cap) in layered soils to lateral loading. The model allows development of p-y curves for the single pile based on soil-pile interaction by considering the effect of both soil and pile properties such as pile size, shape, bending stiffness, and pile head fixity condition. In the model, clay is assumed to respond under undrained conditions considering the effect of porewater pressure, and sand is subjected to drained condition. Series of formulations has been developed to assess the undrained behavior of saturated sand from its drained response, and to predict the potential of sand to liquefy under various situations. The model has shown the capability to evaluate soil response due to both the near field porewater pressure around the loaded pile and free-field excess porewater pressure due to level ground earthquake shaking after Seed. The assessed results foretell that the behavior of laterally loaded piles is function of both soil and pile properties and is influenced by the level of porewater pressure build-up in the soil surrounding the pile.
