GGU-CANTILEVER: Berms

The program can handle 40 berms on both the active and the passive sides of the wall. The berms may include surcharges. The effect on earth pressure is taken into consideration according to the Piling Handbook (Krupp Hoesch Stahl).

The following relationships apply for the parameters x and y:

x = kah0 / (kah β - kah0) · a

y = kah0 / (kah β - kah0) · x

Δeahu = γ · dh + surcharge

γ = unit weight of soil in the berm area

If the angle β is greater than φ, it is assumed that β = φ for analysis. Berms on the passive side are dealt with in the same manner.
