Abstract: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.
