Physical Modelling of Vibro-driven Piles in Sand
Physical Modelling of Vibro-driven Piles in Sand
Vibro-driving is increasingly being seen as a method for installing monopiles for offshore wind turbines. It is a dynamic installation technique known for its quick pile installation in sand that is associated with lower acoustic emissions compared to traditional impact hammering. The risk of pile run is reduced as the pile is clamped to the vibro-driver, which is suspended from the crane. Measured data from vibro-driven installation of large cylindrical piles offshore is limited, such that significant uncertainty remains regarding both vibro-drivability and stiffness of the foundation after installation. Physical modelling can provide measured data from pile tests performed under carefully controlled conditions. This contribution draws on data sets from two completely independently conducted series of vibro-driven pile tests in saturated sand at different modelling scales. The comparison aims to increase confidence in the physical data obtained and the testing techniques used, and by connecting the two data sets significantly adds to the publicly available database of cylindrical piles installed by vibro-driving in sand.
