Series of vertical loading tests were conducted on the groups of 4 piles of three basic types, consisting of (1) pile toe model (subjected only to bearing resistance at pile toe), (2) pile shaft model (subjected only to skin friction), and (3) entire pile model (subjected to both types of resistance). The tests were conducted in a pressurizing tank in which the sand bed was prepared by 'sand rain' method. The deformation modulus of the sand bed thus prepared was obtained directly from triaxial compression tests. Together with the results of these tests, the paper also presents comparisons between measurements and the behavior predicted by non-linear analysis based on finite element method proposed by one of the authors. The analysis accounts for the elasto-plastic state corresponding to generalized strain in soil elements. It is found that the predicted behavior is in fairly good agreement with model test results.
