Equivalent fluid pressure
Equivalent fluid pressure
(OP)
I will soon be constructing a precast foundation system. The precaster's caveat is "Backfill must not exceed 60 pounds per cubic foot equivalent fluid pressure.."
I had intended on backfilling some areas with 3/4" clean stone.
Can someone help me along in how I figure out if this is acceptable??

RE: Equivalent fluid pressure
This does not consider the effects of a surcharge or high water table. This would cause the stress to exceed the required values.

You do not mention whether there is an additional loading from a sloping backfill.
Simply consult your geotechnical engineer .. this is a simple question to answer, and he should be abel to provide you with a more educated answer.
Good luck
