• Abstract:
  Over the past 20 years, drilled shafts have demonstrated increasing popularity over driven ; precast piles. Drilled shafts can accommodate a wider range of sizes, and noise and vibration ; during construction are significantly reduced. On the other hand, when installing driven piles, a ; large amount of data is collected which gives engineers greater knowledge of the soil and rock ; that the pile is being set in. This allows them to adjust designs to create a more secure foundation. ; Obtaining this information when using drilled shafts is more complicated and expensive. Because ; structure and strength of bearing layers vary so much in Florida, increased knowledge of the ; material that will support a drilled shaft, acquired as part of the drilling process, would be very ; helpful for designers and construction. In field and laboratory investigations, University ; of Florida researchers focused on developing and ; evaluating drilling parameter data as a means of ; estimating rock strength.
