EFFECT OF SHAPE AND VOLUME ON THE CAPACITY OF MODEL PILES IN SAND

This report presents load test results on instrumented model piles, both straight-sided and tapered, driven into Standard Ottawa sand in both loose and medium dense states. The distribution of load between pile points and walls, as the over-all pile capacities at various depths of embedment, were studied. Tests revealed continous changes in the intensity of unit load transfer through the walls as the piles were advanced. These changes, as well as the limited ability of the straight-sided piles to transfer large loads through their walls, are presumed to be the result of the development of a system of arching in the sand surrounding the piles. The most interesting and as yet unexplained results obtained in these tests revealed that for all piles straight-line relationships exist between embedded pile volumes and their capacities.
