<p>Soil behavior is complex and thus requires quantification by a reasonably good number of different engineering parameters. Consequently, the seismic piezocone test (SCPTu) is particularly well-suited to being an efficient and economical tool for routine ...

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 ...

Seismic piezocone penetration tests (SCPTu) with dissipation phases are particularly useful for geotechnical site characterization as they provide four independent readings with depth from a single sounding, as well as time-rate information. Methods of evaluating ...

Recent research shows that G0 applies to both static and dynamic properties, as well as to both undrained and drained loading conditions in geotechnical situations. Since the traditional penetration readings from the cone correspond to failure states, an entire ...

Laboratory and field measurements of the small-strain shear modulus of a Piedmont residual soil were compared to gain a better understanding of mechanisms affecting stiffness. Resonant column tests were performed to study influences of void ratio, overconsolidation ...

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 ...
