Abstract In this paper, the ultimate pullout capacity of single isolated helical anchor resting in homogeneous soil deposit with different helix configurations is determined using finite element analysis. The anchor is pulled to its ultimate failure controlling the displacement. Eight different types of anchor configuration are considered in the analysis, where mainly the number of helical plates, the depth of upper- and lowermost helical plates, and the ratio of spacing between the helical plates to the diameter of the plate are varied. The variation of load–displacement curve for each anchor configuration is obtained, and subsequently, the ultimate uplift capacity of each anchor is determined by using double-tangent method. The soil is assumed to follow Mohr–Coulomb failure criteria. The present theoretical observations are generally found in good agreement with those theoretical and experimental results available in the literature.
