Downdrag on Continuous Flight Auger (CFA) Piles Due To Liquefaction

The supplemental funding will support the continuation, data analysis, and documentation of additional field testing of continuous flight auger (CFA) pile downdrag in liquefaction conditions by Brigham Young University. The additional field testing includes axially loading the piles and blasting the site to represent pore pressure generation and dissipation due to liquefaction. Two reports will be developed as a result of this research, including an overview of the testing and an evaluation of methods to estimate downdrag due to liquefaction.
