Thanks for the replies. @ moe333, is the Pah value more a function of the hydrostatic pressure (which would be reduced by the porous material and drain tile) or purely a function of the soil density? I see an argument here...
Hello,
We are looking to design a cantilever retaining wall as efficiently as possible out of reinforced concrete. Pah (Active) is the active horizontal component of the soil pressure behind the wall. In our situation, the backfill soil contains water and has a density of 138 pcf.
