Cantilever sheet pile walls are frequently used for retaining
small height of granular soil in river protection walls,
excavation and as temporary supports in foundation construction.
Sheet pile walls resist the overturning moment
due to pressure from the retained soil by developing a
restraining moment due to passive pressure at the base
along the embedment length of the wall. In the deterministic
design procedures of sheet pile walls, the penetration
depth is determined satisfying equilibrium of moments
and horizontal forces.
Uncertainties in the geotechnical design exist in estimating
in situ engineering soil properties and determining subsoil
profile and boundary conditions. The traditional way
of dealing with the uncertainties is to use conservative values
of the uncertain quantities and/or safety factors. Owing
