To enhance the anchoring capacity of gravity anchors
a novel perforated gravity anchor was proposed. Numerical analysis methods were employed to study the effects of foundation perforation rate ()
number of perforations ()
and perforation shape () on the anchoring capacity of gravity anchors in homogeneous saturated clay. An empirical formula was established to determine the anchoring capacity. The study found that with a fixed number of perforations
both horizontal and uplift anchoring capacities of the foundation decrease with increasing porosity rate . When the porosity rate R is constant
the horizontal and uplift anchoring capacity coefficients and significantly increase with the increase in . Specifically
growth rate slows and stabilizes when ≥16
while grows slowly for 9<<16 and remains constant when ≥16. The perforation shape has a minor effect on the anchoring capacity. The research results provide a theoretical basis for optimizing the anchoring foundation design of offshore floating photovoltaic systems
ensuring their stability and reliability in harsh marine environments.
