Results from the in situ test correlations and measurements provided a wide range of unit skin friction values for the uniform sand deposit. For comparison to the in situ test determined f_s values, a series of prototype-scale steel pipe piles were driven into the upper portion of the sand...

In order to verify this fact, model tests of negative skin friction were done, using four piles having the following kinds of taper; 10 to 1000,5 to 1000,1 to 1000,and 0 to 1000,i. e. straight. For those tests a small steel bin was used where a base plate supported by piston ...

The model piles were tested in loose dry sand. The soil plugging phenomenon and the Incremental Filing Ratio IFR were studied. The complete setup is manufactured for installing and loading the piles at a constant rate of penetration. The obtained results show that the skin-friction less than ...
SANDLATERAL loadsThe objective of the study was to evaluate the load-settlement behaviour of piles, both with and without the inclusion of a sponge material at the pile base to minimize tip resistance and enhance skin friction. Laboratory experiments were conducted to e...
Sand-pile interface sliding and soil deformation components are distinguished quantitatively. The effects of initial relative density of sand, initial normal load, and constant normal stiffness on the magnitude of the pile skin friction and shear displacement at failure are examined. Results indicate ...
