Today, due to the increase in construction in urban areas and excavation in the vicinity of existing structures, as well as structures such as electricity, power and telecommunication towers that must be built vertically and are affected by the force of the wind, there is a need to create suitable supporting components to control Deformations have increased resistance to traction and overturning and preventing damage to adjacent buildings. In addition to structures such as masts, there are structures such as earthen roofs, which can be used with components such as spiral braces horizontally and obliquely. These guarding structures sew the roofs to the soil around them and create tension against the anchors. They overturn. In this numerical research, according to the results of Hashmati et al.'s (2021) research, regarding the laboratory modeling with the effect of particle size on the uplift capacity of spiral containment in sandy soil and in dense and loose conditions with the software used (Abacus). Validated. By changing the thickness of the spiral plate, the diameter of the spiral plate, the thickness of the spiral support rod, the number of spiral plates, the density of the soil and the depth of the placement of the spiral support in sandy soil were investigated. The results were eva‎luated and compared. Increasing the distance between the spiral plates and increasing the number of spiral plates as well as increasing the soil density had the greatest effect on improving the lifting capacity of the spiral brace.
