A comprehensive review of literature pertaining to p-y curve analysis of laterally loaded piles was conducted. Methods of analysis of laterally loaded piles were reviewed with particular emphasis on the applicability of p-y curve analysis. Various existing procedures for development of p-y curves, and the data on which they are based, were also reviewed. Case histories of well-documented, full-scale, field lateral load tests were identified and the soil conditions in which they were performed were summarized. The applicability of existing p-y curve criteria to western Washington soil conditions was evaluated. Analysis of pile group behavior and full-scale, field lateral load test procedures were reviewed.
