Abstract
Excessive displacement responses of monopiles affect the serviceability of offshore structures. Related to complicated pile—seabed—wave interactions, the actual behavior of monopiles in silty seabed under periodic wave action remains unclear, and relevant studies in the literature are limited. A series of experiments were conducted in a wave flume containing single piles in silty seabed with relative density of 0.77 subjected to regular waves. Two stages of wave loading were applied successively, accompanied by data recording which included pore water pressure, water surface elevation, pile head displacement, and pile strain. Development of pile-head displacement and pore pressure in silty seabed was the main focus, but the effects of pile diameter, pile type, and pile stiffness were also investigated. The experimental results indicate that, in silty seabed, piles of large diameter or with fins accelerate soil liquefaction, resulting in strengthened soil which allows a higher upper boundary of pore pressure. Using fins at deeper locations led to a quick failure of the piles, but the opposite result was observed with an increase in fin dimensions. Once pile-head displacement entered its rapid development period, the wave load calculated via the pile moment was an overestimation, especially for the piles of large diameter.
