Cyclic loading of helical pile as anchor for floating windturbines : centrifuge tests

Résumé

Helical piles are currently used in several countries for onshore applications. In the perspective of the development of floating wind turbines, helical pile should be used as an anchoring system. The understanding of the behavior of this anchoring system is investigated under cyclic loading. Installation phase in a saturated sand, monotonic tension and cyclic behavior are analyzed, based on small scale (1/10) centrifuge models. After a presentation of the experimental device, some parameters are investigated, such as the installation torque for two rotation rates and the displacements under cyclic loading.
