Concrete Wall Soil Loading Question
Concrete Wall Soil Loading Question
(OP)
I have a common reinforced concrete wall between two detention vaults of differing elevations that I am designing. See the attached detail...
The active pressures given by the Geotech were 35 psf unrestrained, and 50 psf restrained for the wall.
My question concerns the portion of wall below the bottom slab of Vault "B" in the attached diagram, between levels 128.00 and 123.5. Considering the presence of the foundation drain, and the surcharge loading of the filled vault above, what lateral active pressure diagram would you impose on the short wall in question? Would you use the 50 psf value times the height of the soil retained clear up to the 142.04 foot level, or something different?
Just trying to get a reality check here... Thanks.

RE: Concrete Wall Soil Loading Question
Bottom line is it's a pretty short span, so the reinforcing is probably controlled by the water above.
