Abstract

Spudcan punch-through in sand-over-clay and stiff-over-soft clay deposits was investigated through centrifuge tests and numerical analyses. The aim was to identify and optimise a spudcan shape that can be effective at easing punch-through. A number of spudcan shapes; varying under side profile, number of holes through the spudcan base, and length of skirt around the bottom periphery of the spudcan; were tested. Overall, only the skirt showed positive influence at easing punch-through. A spudcan with a 0.23 times diameter skirt was proposed for easing punch-through on both sand-over-clay and stiff-over-soft clay, with approaches for assessing corresponding penetrating resistance profiles proposed.
