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 (qT, fs, and ub) reflect soil limit states that are utilized to obtain the side and base components for capacity, while the initial soil-pile stiffness is assessed from measurements of downhole shear wave velocity (Vs) via elastic continuum theory. A recent load test case study is presented for a drilled shaft situated in Piedmont residuum for an interstate highway bridge in Coweta County, GA.
