Nondestructive testing of drilled shaft foundations
Caltrans has shown that gamma-gamma logging is a viable, nondestructive method for detecting defects in drilled shaft bridge foundations. These defects, if left undetected, could contribute to early failure during an earthquake. This form of nondestructive testing is required by Caltrans for all drilled shafts constructed by slurry displacement methods, and is a proven technology in the field. This paper will provide an overview of Caltrans nondestructive testing practices and presents a case study demonstrating defects which can be discovered during construction.
