Quantitative information on the response of soil in natural deposits to lateral loadings was obtained by the performance of field tests in conjunction with theoretical studies and in-situ and laboratory determinations. The field tests utilized a segmental pile, a lateral plate loading device, rigid poles subjected to lateral loads, and full-scale laterally loaded piles. Results of the final series of field tests and analytical studies in the program are presented in this report, along with the design recommendations formulated on the basis of the research. Procedures were developed for the prediction of nonlinear lateral soil pressure-displacement relationships applicable to undisturbed deposits of both cohesive and noncohesive soils using easily measured conventional engineering properties of the soil. These procedures were utilized in the development of design procedures for laterally loaded piles in nonhomogeneous layered soil system. An iterative solution of the laterally loaded pile problem utilizing a digital computer was developed, and a similar iterative solution for hand computations in a tabular form was evolved for use in cases where a computer cannot be used. |
