    NUMERICAL ANALYSIS OF THE FOUNDATION DEFORMATION OF USAF UNDER HORIZONTAL LOADINGS

      Abstract
    • The features of umbrella suction anchor foundation(USAF) are introduced, and the finite element model of USAF is established. Based on numerical simulation results, the foundation deformation of USAF,soil failure mode, the maximum shear stress area and the center of rotation of the anchor body are analyzed emphatically. A comparison has been made between the USAF model and conventional single cylinder suction anchor model and the results show that the umbrella suction anchor foundation(USAF)has obvious advantages in horizontal bearing capacity. It is very application prospect for USAF in offshore wind power engineering.
