An investigation was made to obtain the in-place properties of deep soil deposits with relation to pile foundations subjected to lateral thrust which would result in the verification of the Palmer-Thompson Theory for piles subjected to lateral load. Lateral-load tests were conducted on 16-inch-wide piles in a sand fill and a natural clay deposit. Incremental, repetitive and sustained free-head and fixed-head loadings were applied to a single pile instrumented with soil-pressure and piledeflection gages. Laboratory soil tests were conducted on samples from the pile test sites. The experimental results indicate that the pile-soil system does not respond elastically to a lateral load. Since the Palmer-Thompson Theory is premised on elastic pile-soil behavior, verification of this theory has not been achieved. Author
