Hello,
We made an pullout test (ASTM D3689)on a driven pile with success. The criteria used for the acceptance of the pile is the elastic lengthening + 5mm. I calculated the elastic lengthening with PL/AE, but the bridge engineer says that the elastic lengthening should take into account the soil resistance!? I do not agree with that, but the piles are not accepted until we can give an answer to that, and I do not have arguments. I do not know where to begin either to calculate the ''elastic lengthening'' taking soil resistance into account....
The pile is 14'' diameter pipe pile with 0.375'' wall thickness (356mm x 9.53mm).
Anybody has input to direct me??
Thank you very much in advance.

p.s. You can find the test data joined (in french but it's mostly straightforward)
