In an attempt to improve understanding of the performance of vibro-driven piles, this study identified soil parameters, in situ stresses, and vibro-driver parameters that significantly affect driveability, bearing capacity, and load-movement behavior of vibro-driven piles. The study also compared the performance of vibro-driven piles (with and without restrike) to that of impact-driven piles. It was found that there is an optimum frequency for driving piles using a vibro-driver. For the driver-pile-soil system studied, a unique driving frequency of 20 Hz yielded the highest rate of penetration for the range of soil conditions, eccentric moment, and bias mass forces. These and other study findings are discussed.
