Load Capacity of a Driven Pile
Load Capacity of a Driven Pile
(OP)
Closed end Steel pipe piles were driven in soft silt/clay (14 m and followed by medium dense sand to 17 m. The 5000 Ibs hammer with a fall of 3ft was used. The blow counts changed from 5/ft to 20/ft for the last 2-3 ft of penetration. What is the best estimate of pile tension loads and compression loads. What formula would be suitable.

A common thing happens in many soils is a temporary weakening of side shear strength during driving, so depending on driving resistance probably is not a good idea. Pile spacing also is involved.
For a serious determination start with pull out tests.

How important is the accuracy of this "estimate?" If important, then as kieran1 mentioned, testing is the best route.
