<p>Tapered driven piles have been the deep foundation of choice ever since construction of and at the well-known John F. Kennedy International Airport (JFKIA) in New York City began in the late 1940s. Timber piles were used primarily for many decades but various ...

The axial load-displacement-capacity of drilled shaft foundations can be conveniently evaluated using the results of seismic piezocone penetration tests (SCPTU) to provide continuous profiles of small- and large-strain soil properties. The penetration readings ...

The axialload-displacement response of drilled shaft foundations inPiedmont residual soils can be assessed using an elastic continuum approach. Equivalent elastic moduli measured by flat plate dilatometer tests are shown to provide reasonable deflections at ...

A series of instrumented load test on two drilled shaft foundations situated in residual soil and partially weathered rock of the Piedmont geology were conducted to evaluate load displacement and load transfer response. An extensive array of in situ tests ...
