Abstract

Abstract

As one of the important foundation types of mooring systems in marine structures, rigid anchor piles often bear oblique upward pulling loads, and the mechanism of oblique uplift resistance is more complex than that of flexible piles. Through numerical simulations and theoretical analysis, the influence of loading modes and pile-soil interface friction coefficients on the oblique uplift capacity of anchor piles was studied. Based on the finite element numerical model, the failure envelope surfaces of anchor piles in different loading modes and friction coefficients were obtained, and it was found that the oblique uplift capacity of anchor piles was significantly influenced by loading modes. Due to the limitation of Mohr-Coulomb Constitutive Model, it was difficult for numerical models to accurately simulate the vertical uplift properties of anchor piles with rough appearances. With the increase of friction coefficients, the vertical uplift capacity of anchor piles increased because of the development of fracture toward soil around piles. The horizontal bearing capacity of anchor piles was relatively accurate calculated by the S-shaped distribution hypothesis of soil resistance. Finally, an envelope model of rigid anchor piles was constructed considering the friction coefficients of pile-soil interfaces.
