effect of fill on existing pile capacity
effect of fill on existing pile capacity
(OP)
How does one calculate the effect of 3 feet of additional fill on piles that are already driven. The test pile tested out a 80 tons, but after that the project requirements dictated raising the building for flood reasons.
The piles are 50 feet long are driven thru clay & into sand, primarily skin friction. They are in groups of 2, 3 & 4.
I need info for preliminary look, will use geotech for final answer.

How did you test the test pile? PDA? Static load test? Old, antiquated, unreliable, why-are-people-still-using-it ENR formula correlation?
For your preliminary look, assume the resistance from pile within and above the compressible layers is acting downward, and that the resistance below the compressible soil is activing upwards. Your net ultimate pile capacity is the difference between the two.
