Stresses in a buried pipe

Stresses in a buried pipe

Stresses in a buried pipe

(OP)
This might more belong to the structure section, but I guess it's quite common in geotechnics.
I want to calculate the stresses induced in a thin-walled buried pipe. I am using the usual formula for the hoop stress (see the link): sigma=P*R/t
Also I'm using the vertical total stress for P, as, for sand and no lateral movement, the horizontal stress is smaller.

Is this method correct or is there a more relevant one?

good references, all around.

RE: Stresses in a buried pipe

I thought 'Hoop stress' was a tensile stress in the wall due to internal pressure.

Thanks for the references.
To dicksewerrat: I think that hoop stress is indeed, in most cases, a tensile stress due to internal pressure, but the formula to get it still works if the pressure is external (in which case it becomes compressive). See the remarks in the link on my first post
