    • Abstract
  • Aiming at the problem that the suction force of the suction bucket affects its bearing characteristics during the working process, the suction bucket is required to bear the uplift force of floating structures. Its bearing characteristics are related to the geometrical size of the suction bucket, the strength of the soil layer, the load characteristics and other factors. The bearing characteristics of suction bucket foundations under inclined loads under different aspect ratios and strength distributions are studied based on the finite element method. The relationship among vertical, horizontal bearing capacity coefficient and diameter ratio (L/D) and heterogeneity coefficient of soils K is established. The relevant method is also given. The envelope of vertical load (V) and horizontal load (H) is established, and the method for calculating the bearing capacity under the V-H combination is finally exhibited. The research results may provide a basis for the design of anti-pull-out foundation of marine floating structures.
