Mechanism of Downdrag for Floating H-Pile Subjected to Surcharge

This paper investigates the mechanism of downdrag for floating H-piles subjected to surcharge loads by performing three-dimensional numerical comparative analyses. The constitutive models and model parameters were calibrated using a centrifuge test. The downdrag of the H-pile can be reduced efficiently by enlarging the web properly, but enlarging the flanges was inefficient.
