Improved Prediction of Peak Resistance for Spudcan Penetration in Sand Layer Overlying Clay

A reliable assessment of peak resistance is the key aspect of geotechnical design for spudcan installation in sand-over-clay soil profiles. The most recent failure stress–dependent method has been validated against a large number of centrifuge tests and proved to provide satisfactory accuracy. However, additional centrifuge tests collected in this study indicated that, under certain circumstances, the recently proposed method provides...
