CAD Design Example Stability Computations Ultimate Limit State Internal Stability The internal stability design checks are carried out at every gabion course for Factor of Safety on Overturning :-Fo for Factor of Safety on Sliding :- Fs for Eccentricity :- e for outer bearing (toe) for inner bearing (heel) The Factor of Safety against Sliding at each course is computed considering the effective frictional angle on gabion to gabion interface is 35 degrees. The minimum acceptable Factor of Safety against Sliding between courses ignoring any contribution of the wire is 1.3 The minimum acceptable Factor of Safety against Oveturning at each cousre is 2.0 excluding any contribution of the mesh or joint strength. The eccentricity at each level must lie <strong>with</strong>in the mid third, in the case of a flush faced vertical wall the eccentricity should be proportioned between 0m at the top of the wall to <strong>with</strong>in the mid third at the base, in both cases if value is negative and outside the mid third the value is acceptable. The bearing value at the back face must be positive.
