Available in PDF, EPUB and Kindle. Book excerpt: A method previously presented by the author (in ASTM STP 154) is generalized to encompass soils having nonlinear p-y characteristics. This results in a method that can handle, but is not restricted to, pile-soil systems having (1) piles greater than 9 m (30 ft) in length having free, fixed, or partially fixed heads, and any cross-sectional shape and length relationship, for example, constant, tapered, or stepped, and of any materials or combination of materials; (2) soils of any variation with depth, whether homogeneous, stratified, or combinations thereof, and having p-y characteristics of any nature; (3) ability to qualitatively and quantitatively predict behavior and stresses under static, fluctuating, and repetitive lateral loadings, or where larger emergency loads can be interspersed between normal loads. Ways are suggested for dealing with each of these factors. In addition, a method is proposed for obtaining the effective soil constant at a given site for a range of lateral loads, using empirical test data from free-head piles of the same characteristics subjected to lateral loads. The method is validated by use on previously published data of a comprehensive series of tests on free-head piles by Assadeh and Davison (Journal of the Soil Mechanics and Foundation Division, Proceedings of the American Society of Civil Engineers, Volume 96, No. SM5, Sept. 1970, pp. 1583-1603). Using the soil constants resulted in computed load-deflection curves closely approximating actual data. These constants are used in turn to compute the expected deflections and pile stress of those same piles under fixed-head conditions.
