CPT-14 in Las Vegas, Nevada
Crystal Cox and Scott Barnhill will be attending CPT-14 in Las Vegas this May. Their paper titled " Axial pile capacity within an elastic continuum framework in Virginia’s Coastal Plain" will be included in the proceedings.
This paper presents a case study of the load-displacement-capacity response of augercast concrete piles installed in layered soils of Virginia's Coastal Plain within the elastic continuum framework. Using this approach a nonlinear representation of load-displacement-capacity response under axial compressive loading is provided. The sixteen inch diameter augercast concrete piles were subject to traditional top-down static axial compressive load tests. Pile capacities were directly calculated using Laboratiore Central des Ponts et Chaussées (LCPC) methods. Analysis under the elastic continuum theory was conducted to calculate estimated theoretical pile displacements. The measured pile displacement values from load testing were in close agreement with the calculated theoretical displacement values. Theoretical values were found to be closer to the measured values from load testing when using correlated shear wave velocities as opposed to using directly measured shear wave velocities from Seismic Piezocone Penetration Testing (SCPTu).
