This report examines the use of strain wedge (SW) model formulation to evaluate the response of single piles or groups of piles in layered soils under lateral static loading. Application of the model provides behavior prediction under a wide range of strain or deflection. In this study, the capability of the SW model is extended to predict the response of a single pile or pile group under lateral loading in liquefied soil. The results from the tests suggest that the behavior of laterally loaded piles is both a function of soil and pile properties and is influenced by the level of porewater pressure that is built up in the soil surrounding the pile. Under these conditions the capacity of a loaded pile or pile group might drop significantly under such conditions.
