Retaining Wall with downward sloping backfill?
Retaining Wall with downward sloping backfill?
(OP)
How do I calculate the passive and active coefficients for a retaining wall with a downward sloping backfill. If you know, can you point me to a good reference?
Essentially, what I want to calculate is the resisting force of a "wedge" of rock or soil up against a vertical face. The "wedge" would have a defined height and slope.
All I can find is theory for straight and inclined backslopes and short of deriving my own theories, I haven't been able to come up with a solution. It seems simple enough though...unfortunately, I don't feel confident enough in my knowledge of the theory to develop it myself.

Thanks for the tip on the vulcanhammer design manual. It does have a nice concise table for Ka/Kp respective to phi for granular soils. Unfortunately, my case is cohesive....which means I need to get into a trial wedge analysis (I think).
Regarding respectable texts...while I don't have an exhaustive collection, my Das text and other design manuals (COE) do not list have any negative angles in their tables....
