Experimental and numerical investigation on cavity formation from large rectangular spudcan penetration in clay

At present, the research on the cavity formed by spudcan penetration is based on two-dimensional axisymmetric analysis of circular spudcans, and it is doubtful whether the results could be applicable to rectangular spudcans. In this paper, centrifuge experiments and finite element analysis are combined to study the penetration process of large scale rectangular spudcans in the clay with undrained shear strength varying with depth.
