Lateral Pressure of Mulch
Lateral Pressure of Mulch
(OP)
Anyone have any estimates to the weight and/or Ka and/or c values for mulch or even a Equivalent Fluid Pressure.
I found a couple of papers but one lists the phi of mulch at 45 degrees while the other lists it at 14 degrees with c = 12 psf.
This paper used direct shear tests

This paper used tilt table

Any other thoughts on why these are so different?
Thanks!
