A timber pile of length 8m and
diameter of 0.2m is driven with a 20
kN drop hammer, falling freely from a
height of 1.5 m. The total penetration
of the pile in the last 5 blows is
40mm. Use the Engineering News
Record expression. Assume a factor of
safety of 6 and empirical factor
(allowing reducing in the theoretical
set, due to energy Losses) of 2,5 cm.
The safe Load carrying capacity of the
pile (in kN, round off to 2 decimal
places) is
