• Abstract:
  Driven piles are commonly used in foundation engineering. Pile driving formulae, which directly relate the pile set per blow ; to the capacity of the pile, are commonly used to decide whether an installed pile will have the designed capacity. However, ; existing formulae have been proposed based on empirical observations and have not been validated scientifically, so some ; might over‐predict pile capacity, while others may be too conservative. In this report, a more advanced and realistic model ; developed at Purdue University for dynamic pile driving analysis was used to develop more accurate pile driving formulae. ; These formulae are derived for piles installed in typical soil profiles: a floating pile in sand, an end‐bearing pile in sand, a ; floating pile in clay, an end‐bearing pile in clay and a pile crossing a normally consolidated clay layer and resting on a dense ; sand layer. The proposed driving formulae are validated through well documented case histories of driven piles. ; Comparison of the predictions from the proposed formulae with the results from static load tests, dynamic load tests and ; conventional formulae show that they produce reasonably accurate predictions of pile capacity based on pile set ; observations.
