Tilt I
Horizontal Deflection at To of Wall due to settlement of soil
(Deflection due to wall bending not considered)
Soil Spring Reaction Modulus 250.0 pci
Horizontal DO @ Top of Wall (approximate only) 0.035 in
The above calculation is not valid if the heel soil bearing oressure exceeds that of the toe,
because the wall would then tend to rotate into the retained soil.
