Effect of Backslope on Retaining Wall
Effect of Backslope on Retaining Wall
(OP)
I have a stacked block gravity retaining wall with a 10 degree backfill slope. When I am calculating the pressure on the wall from the soil what height of backfill do I use?

Find a good book or Google retaining wall calculations.

Backslope angle is Beta in the equations.

You will also need to check the overall stability of the slope.

If it is an MSE wall and your using NCMA design then the Ka value will be calculated using Coulomb equation which will reflect the backslope condition and therefore your height is H (the total height of the wall at back of wall).
Also see NCMA's Design manual for segmental retaining walls.
