The Action of Soft Clay along Friction Piles

Data are presented herein on the increase in supporting capacity of a pipele with the passage of time, the distribution of applied loads along the pile, and the pore-water pressu res developed in the soil adjacent to the pile when given into soft, saturated clay. Soil test data are interpreted to determine the effect of pile driving on the clay and the resis tanc e of the clay to movement the pile. A procedure is prese nted for using the results of vane shear tests determine the relationship between load and settlement for a pile driven to clay.
