FLAT DILATOMETER MODULUS APPLIED TO DRILLED SHAFT FOUNDATIONS IN PIEDMONT RESIDUUM (1999)

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 "working loads" when evaluating settlements for axial compression loading. Load transfer to the base is also evaluated. Two case studies involving field load testing of end-bearing and friction-type drilled shafts in Atlanta, Georgia are presented.
