Performance of Helical and Square Plate Anchors in Cohesionless Soil
Anchors have been developed for various purposes such as strengthening the slopes, retaining walls, stability of tunnels, and stability of foundations. There are many types of anchors depending on the type of load, type of structure, and local subsoil conditions. The behavior of anchors in the field indicates that the collapse mechanism and bearing capacity of the anchor can be determined by many factors. Most studies focus on massive models shaped anchor plates with various shapes (Helical, square) with a variation of the dimensions, depth, and type of load. In the present investigations, the uplift capacity of helical and square plate anchor resting in cohesionless soil deposit with different plate configurations was determined experimentally. Different types of anchor model were cast for experimental study, where mainly the number of plates, the depth of upper- and lowermost plates, and the ratio of spacing between the plates to the diameter of the plates were varied, and ultimate uplift and lateral capacity of each anchor was determined. In experimental investigation the uplift and lateral load carrying capacity of square and helical plate anchors are found to be increased with increase in embedment depth and spacing between the plates. In the present study the helical plate anchor system is more efficient than square plate anchor system as they are providing more uplift and lateral load-carrying capacity.
