    Abstract

    The performance of spudcan foundations for jack-up platforms in intermediate soils is evaluated with a combination of experimental and numerical techniques. Given the possibility for these foundations to experience variable periods of load­ hold, attention is drawn to the effects of consolidation on spudcan installation and subsequently its combined capacity under multi-directional loading. The implementation of a hypoplastic constitutive model for structured clays underpins the numerical analyses, with outcomes validated by an extensive geotechnical centrifuge testing campaign. The results reveal a general increase in the spudcan mono and multi-directional capacity, due to strengthening and stiffening of the soil.
