Consolidation settlement of piles/caissons
Consolidation settlement of piles/caissons
(OP)
I was wondering whether anyone knew of a good method to calculate the settlement of piles and/or caissons, specifically the long-term primary and secondary consolidation.
I've created something in spreadsheet format using basic consolidation theory as a start and essentially reducing the load based on the caisson friction. However, I was wondering what else was out there (besides FEA).
Thanks in advance for any help.

Fellenius also has some free downloadable papers / publications that are real helpful, but not quick or easy.
The main simplification is the equivalent rigid footing for the pile group at a specific depth below the pile cap - usually 2/3 the pile length for friction piles. The it's soil mechanics (as if no piles but a recessed mat foundation).

The, "Friction" of a pile transfers an increased vertical load on the adjacent and underlying soils. That transfer of stress WILL lead to some compression, consolidation, or otherwise settlement. Not sure of your comment, but it doesn't resonate with me as written.
Then again. . .

Going back to the original post, the question is about consolidation and piles. Consolidation is considered apart from, and not because of, the friction interface. That is, the consolidation settlement is from the soil (imaginary footing) near the bottom portion of the pile, not an interface slip.
