摘要

为提高锚固基础的锚固力,提出新型开孔重力式锚,采用数值分析方法研究均质饱和黏土中基础开孔率R、开孔数量N和开孔形状S对锚固力的影响规律,建立确定锚固力的经验公式。研究表明,当开孔数量N一定时,基础水平和抗拔锚固力整体上均随开孔率R的增加而降低;当开孔率R一定时,基础水平和抗拔锚固力系数N_cH、N_cV随N的增加而显著增长,其中N_cH在N≥16后增长速率减缓并趋于稳定,N_cH在9<N<16时增长缓慢、N≥16后保持不变;开孔形状对锚固力的影响较小。

Abstract

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 （R）, number of perforations （N）, and perforation shape （S） 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 N, both horizontal and uplift anchoring capacities of the foundation decrease with increasing porosity rate R. When the porosity rate R is constant, the horizontal and uplift anchoring capacity coefficients N_cH and N_cV significantly increase with the increase in N. Specifically, N_cH growth rate slows and stabilizes when N≥16, while N_cV grows slowly for 9<N<16 and remains constant when N≥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.
