Retaining wall loads
Retaining wall loads
(OP)
Hi all, We all know that the force on a retaining wall depends on the depth of the water / soil it retains, my question would be why is the Width of the soil/water being retained (the dimension perpendicular to the soil/water) is not considered? I am a bit rusty when it comes to fluid and soil mechanics, can somebody guide me on this?
Because I think the width of the soil or water to be retained has a significant on the retaining wall loads. Please see attached sketch. Would figure A resist the same force as figure B?

Try to search Narrow wall or for MSE type walls try MSE with stable feature.
I started a post here and will come back to this and try to give a more though discussion, hopefully in the near future when I get some more free time.
As for the water case is you had a wall of water that was say less than 1' thick I believe you would have a reduced pressure as the weight of the water cube is less than 1 cuft

Re: water, this seems intuitively right, but is incorrect. Consider what happens if you measure in psi instead of psf. Attached is an explanation.

As far as water pressure behind a wall, it is independent of the depth perpendicular to the wall. A column of water exerts pressure based on gamma * H.
