Predicting the penetration of spudcan footings during jack-up platforminstallation often requires bearing capacity calculations in layered soil profiles. This article considers the particular case of a rough footing resting on a clay layer overlying a rigid base (which leads to lateral squeezing failure of the top layer); the clay is of linearly increasing shear strength with depth. Computational limit analysis, as implemented in the software package LimitState:GEO, as well as 2D finite element analysis, are used to undertake a broad parametric study of the problem. The bearing capacity factors obtained in plane strain conditions from numerical analysis are compared to a closed-form upper-bound solution derived from classical theory of plasticity. The discussion is then extended to axisymmetric foundations based on finite element results. In a second part of the study, the effects of combined VH loading on the footing bearing capacity are discussed for homogeneous soil conditions; an empirical analytical expression is proposed to fit the numerical results.
