Effects of Downdrag on Pile Performance

The primary objective of the proposed study is to instrument, monitor and collect data from piles behind embankments that are anticipated to have measurable amounts of downdrag force and settlement (new construction) with the motivation of determining under what circumstances downdrag is a critical load and when it is not. A secondary objective focuses on refining the Florida Department of Transportation (FDOT) design criteria for the inclusion of downdrag computations.
