Abstract The bearing mechanism of the large diameter monopile and the one with wings is studied through centrifuge tests. Based on the large diameter monopole which is widely used in the offshore wind turbine，the wings are added with the large diameter monopole in order to use the soil resistance of the shallow soil as far as possible. Nine centrifuge tests are conducted for the sake of studying the horizontal bearing capacity of the large diameter monopile with wings. The horizontal bearing capacity h changes as the dimension and the embedded depth of the wings and the loading direction are different. The study results show that the horizontal bearing capacity of the large diameter monopile with wings is much more than that without wings. The amplitude of the enhancement is in connection with the dimension and the embedded of the wings. The research results provide a reliable evidence for the design and construction of the large diameter monopile with wings for offshore wind turbine.
