“…Increased contact area between the anchor pile and soil. Emirler et al 35 used numerical simulations to study the uplift resistance capacity of piles with variables embedded depth in sand and found that the area of effect of the anchor pile on the sand surface increased with an increase in the embedded depth. Although in this study, the effect of the anchor pile under oblique load differs slightly from the above research, increasing the embedded depth still increases the uplift resistance capacity of the anchor pile.…”

Anchor piles are widely used in marine aquaculture, and the safety is largely determined by the uplift resistance capacity,especially in harsh ocean environments. However, there are few practical guides to the design and installation of the anchor piles for mooring the body of marine aquaculture equipment. Laboratory experiments were conducted to investigate the effect of the initial tension angle, pile diameter, embedded depth, and pile configuration on the uplift resistance capacity of anchor piles under oblique loads. CCD camera and load cell were utilized to measure the corresponding displacement and load, respectively. The results show that increasing the initial tension angle of circular and square single piles can significantly improve the uplift resistance capacity. The failure load of the square single pile was slightly higher than that of the circular single pile. Increasing the pile diameter can effectively improve the failure load and delay the development speed of the pile top displacement. Increasing the embedded depth can effectively improve the failure load and increase the lateral displacement of the pile top. The uplift resistance capacity of the dual anchor piles was better than that of the single anchor piles. The layout configuration has little effect on the failure load, but has a large effect on the displacement development.

“…Increased contact area between the anchor pile and soil. Emirler et al 36 used numerical simulations to study the uplift resistance capacity of piles with different embedded depths in sand and found that the area of effect of the anchor pile on the soil surface increased with an increase in the embedded depth. Although in this study, the effect of the anchor pile under oblique load differs slightly from the above research, increasing the embedded depth still increases the uplift resistance capacity of the anchor pile.…”

Anchor piles are widely used in marine aquaculture, and their uplift resistance capacity largely determines their safety, especially in harsh ocean environments. However, a practical guide on its design and installation is wanting. Laboratory experiments were conducted to investigate the effect of the initial tension angle, pile diameter, embedded depth, and pile configuration on the uplift resistance capacity of anchor piles for marine aquaculture under oblique loads. The results show that increasing the initial tension angle of circular and square single piles can significantly improve the uplift resistance capacity. The failure load of the square single pile was slightly higher than that of the circular single pile. Increasing the pile diameter can effectively improve the failure load and delay the development speed of the pile top displacement. Increasing the embedded depth can effectively improve the failure load and increase the lateral displacement of the pile top. The uplift resistance capacity of the dual anchor piles was better than that of the single anchor piles. The layout configuration has little effect on the failure load, but has a large effect on the displacement development.

“…Estacas cravadas deslocam o solo à medida que o penetram, provocando compactação do solo entorno da estaca e conferindo maior resistência no contato, quando comparada com estacas escavadas. Emirler et al (2019) estudaram o comportamento de estacas com 2,5 cm de diâmetro, cravadas em areia, variando o material da estaca (aço, alumínio e delrin), a relação L/D (8, 12 e 16) e a densidade relativa da areia (30%, 50% e 80%). Para tal fim, foi realizada uma série de análises aplicando o método dos elementos finitos através do programa Plaxis 3D.…”

Fundações com solicitações de carregamentos de tração ocorrem em torres de transmissão, chaminés altas, estruturas de cais, sistemas de ancoragem offshore, etc.. A capacidade de carga de uma estaca submetida à compressão é bem documentada e investigada na literatura, o mesmo não pode ser afirmado para carregamentos à tração. Este artigo apresenta os principais trabalhos relacionados ao comportamento de estacas isoladas em areia submetidas a tração axial. Os principais métodos de dimensionamento são apresentados e é feita uma discussão sobre os parâmetros que influenciam a capacidade de carga da estaca, como ângulo de atrito do solo, atrito na interface solo-estrutura, densidade relativa da areia, relação L/D, onde L é o comprimento da estaca e D o diâmetro, entre outros. PALAVRAS-CHAVE: Estacas, capacidade de carga axial à tração, fundação.ABSTRACT: Foundations subjected to uplift loads can occur in transmission towers, tall chimneys, pier structures, offshore anchoring systems, etc. The load capacity of a pile subjected to compression is well documented and investigated in the literature, the same cannot be stated for uplift loads. This article presents the main works related to the behavior of isolated piles in sand submitted to pullout forces. The main predicting models are presented and the parameters that influence the load capacity of the pile are discussed, such as soil friction angle, soil-pile friction angle, sand relative density, embedment ratio, etc.
