Abstract
This study is to investigate behaviours of winged monopiles subjected cyclic loading in a calcareous ground through numerical analyses. In the analyses, axial load tests (push-in or pull-out) of monopiles with and without wings in a calcareous ground are simulated using a three-dimensional finite element program, PLAXIS 3D. Triaxial tests on a calcareous ground sampled in Vietnam are carried out prior to the analyses of the load tests to investigate the mechanism behaviours of the calcareous ground and to select an appropriate soil model as well as to evaluate the corresponding soil parameters. In this study, the hypoplastic model is used to model the ground. Interface elements are employed to simulate the slippage between the pile shaft and the soil. The analysed results show that the resistance of the winged pile is considerably higher than that of the pile without wings.
