“…This anchor may be put into practically any kind of soil to generate a huge concentrated force, although in certain foundations the force that operates is a tensile force rather than a compressive force. Because the soil cannot bear the draw, an armature system is employed on the ground where the pulling force or pulling force is kept by the armature which is planted deep into the ground [11]. According to the definition above, the anchor is a component of the structure that works to transfer tensile tension from the main structure to the soil layers around the anchor [12].…”

The purpose of this research is to develop a folding anchor model, which is a modification of the star-shaped plate anchor, and to investigate the pull-up capability operating in cohesive soils. Physical testing is performed in the laboratory and on a full scale in the field, with the findings of the pull-up capacity achieved compared. The anchor model is made up of four leaves with varying widths and depths. It is flexible and may be closed and opened like an inverted umbrella. The effective area of each anchor was determined in laboratory experiments to be A1=30.00, A2=57.60, and A3=147.20 cm2, evaluated in a test column bath and filled with statically compressed, cohesive soil in four layers to a height of 30 cm. Each model was evaluated at three different depths: 30, 60, and 90 cm. The effective area of each anchor in field testing is B1=57.60, B2=147.20, and B3=600 cm2. The qualities of the soils chosen in the laboratory and in the field are identical. Each model was tested at three different depths: 100, 200, and 300 cm. The most resemblance to pull-up test results was found in laboratory and outdoor testing. The findings indicated that the area of each anchor model increased at each depth, resulting in a considerable rise in pull-up load. The change in depth of each anchor variation, however, did not result in a substantial increase in pull-up load. This implies that the folding type model anchors do not need extensive design. Each area change has a fundamental constraint in that adding depth will no longer result in a higher maximum pull-up capability. It also shows that these anchors are relatively simple to install in the field using basic tools without excavating or drilling the soil. Doi: 10.28991/CEJ-2022-08-09-07 Full Text: PDF

“…Because of its excellent bearing capacity and deformation resistance, the vertical plate anchor is often used in permanent anchoring engineering, such as retaining walls, sheet piles, etc. [1,2]. Because the bearing capacity design has been a focus [3], the bearing behavior of vertical plate anchors becomes critical for its theoretical basis signi cance.…”

Vertical plate anchors are an effective technique to enhance the stability of various structures, such as retaining walls and sheet piles. More research has been devoted to their bearing capacity and macroscopically affecting parameters, while less research can be found on their microscopic bearing behavior. In this paper, the microscopic bearing behavior of vertical plate anchors subjected to a horizontal pullout load in sandy soil was investigated with the particle flow code (PFC) based on the model test results. Results show that the larger-sized anchor plates withstand greater soil pressure and affect a broader range of soil during the pullout process. The soil not behind the anchor plate is pressed, and the pressure in front of the anchor plate increases with increasing size. The soil close to the plate anchor suffers larger pressure while the soil far away from the plate anchor is less affected, and the soil is redistributed to a more stable state during the pullout process of the plate anchor. The particles with a long axis distributed in the horizontal direction are the most stable, while those with a long axis distributed in the vertical direction are the most unstable.
