Abstract : This technical report documents the findings of an investigation into the effects on the axial capacity of piles driven by vibratory pile driving hammers. The investigation stems from the concern that foundation engineers in the Lower Mississippi Valley Division of the US Army Corps of Engineers had over the unexpected low capacities found during the pile test at Red River Lock and Dam No. 1. While driving piles with a vibratory hammer increased productivity up to 10 to 20 times over the use of an impact hammer, there is a significant reduction in the axial capacity of the piles driven with a vibratory hammer. The study revealed that this reduction was a result of a loss in the load carried by the tip. The report documents a number of pile testing programs that were performed to make direct comparison between vibratory-driven piles and impact-driven piles.
