This work was performed in support of the AUTC project “Utilization of Screw Piles in

High Seismicity Areas of Cold and Warm Permafrost” under the direction of PI Dr. Kenan

Hazirbaba. Surface wave testing was performed at 30 sites in the City of Fairbanks, AK from

August 9-13, 2009 by personnel from the University of Arkansas. The goal of the testing was to

develop shear wave velocity profiles at selected research sites and at various areas of cold and

warm permafrost. The shear wave velocity profiles provide a key parameter in determining the

dynamic response of piles and soil-pile interaction under dynamic loading. The Spectral Analysis

of Surface Waves (SASW) method (Stokoe et al., 1994) was used to determine shear wave

velocity profile at each site to a depth of between 30 and 60 meters.
