Acceptance Testing of Drilled Shafts by Gamma-Gamma Logging
Publication: Geotechnical Engineering for Transportation Projects
Abstract
Non-Destructive Evaluation (NDE) of drilled shafts constructed under slurry is essential to verify constructed pile integrity. The function, application, and limitations of non-destructive testing of drilled shafts and the mitigation of detected anomalies will be highlighted by three illustrative case studies from California highway bridge projects. Special attention will be directed to the use of Gamma-Gamma Logging (GGL) for evaluation of shafts constructed under wet conditions. Gamma-Gamma Logging will also be compared to Crosshole Sonic Logging (CSL), with the relative merits and limitations of both GGL and CSL methods.
