• The response of skirted foundations to combined vertical (V), moment (M) and horizontal (H) undrained loading is investigated using finite element and upper bound plasticity analysis. The study has focused in particular on the effect of the foundation embedment depth on the size and shape of the combined V-M-H yield locus. The yield locus was found to be of similar shape to that of a surface foundation but the size of the yield locus was increased. Normalisation of the yield locus by the single load bearing capacities (V_0,M_0 and H_0) allowed the yield locus to be generalised for varying soil profiles and footing embedment depths. Upper bound plasticity analysis was carried out to calculate V_0,M_0 and H_0 for a range of footing embedment depths and undrained soil shear strength profiles and design charts are presented for their determination.
