On the Study of Pile Driving Formula Based on Blow Counts ...
Nov 14, 2010 · The model piles used were steel pipe piles of 34,,,, and mm in diameter and were driven up to a depth of 8–10 m using drop hammer and the number of blows were recorded for every 300 mm penetration. This hammer blow counts were used to calculate the predicted pile bearing capacity using the pile driving formula.
