Coupling of centrifuge and numerical modeling to analysis of bearing mechanism. A prior dynamic loading with small amplitude increased stiffness of foundation. Subsidiary axial force was proportional to distance from pile to load axis. General effect of multiple piles played a dominant role in bearing capacity. Stronger superstructure increased percentage of general effect with tendency to 1.
