Downdrag on Continuous Flight Auger Piles Due To Liquefaction
Project Information
Project ID:
FHWA-PROJ-14-0009
Project Abstract:
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.
Goals:
The primary objective of this contract is to team up with Brigham Young University (funding also through National Science Foundation and Pacific Earthquake Engineering Research) to utilize three instrumented 0.6-meter diameter CFA piles installed at a Christchurch, New Zealand test site to perform load tests before, during, and after blast-induced liquefaction.
