Helical Pile Shafts
Helical Pile Shafts
(OP)
This is not project specific, but a request for opinions.
I have been working with a structural engineer that has expressed his dislike of helical piles. His concern is this: He feels the auger going through the soil disturbs it, leaving the pile shaft "unsupported". He worries that the relatively thin shafts would then be subject to buckling, especially if there is any sort of lateral load.
Obviously, this system has been used extensively, has been load tested under various conditions, and has been givin allowable capacities
I have my thoughts on the subject, but thought I would get a more broad opinion. The main topic involves the soil disturbance/bucling issue, but other opinions concerning helicals are welcome. Thank you for your input.

RE: Helical Pile Shafts
ADSC (Association of Drilled Shaft Contractors recently had a study done by Allen Cadden and Jesus Gomez of Schnabel Engineering. The study concerned buckling of relatively small diameter micropiles. Check the ADSC web site. I think their paper is available there.
