A plastic limit formulation was previously developed for estimating caisson uplift in cohesive soils under general conditions of vertical, horizontal, and inclined loading. The formulation considers the effects of soil shear strength profile, caisson aspect ratio, anchor line attachment depth, and load inclination angle. Load capacity predictions from the plastic limit analyses are compared to data measured in seven centrifuge tests in which model caissons are subjected to purely vertical and inclined loads of various orientations. The effect of a bevel at the caisson tip is also investigated. Comparisons are also made to finite element predictions.
