| Abstract: | Screw anchors have been used in various applications including tower foundations of transmission lines and excavation bracings.Experimental studies on the anti uplift capacity of single screw helical anchors in sand and clayey sand are presented.Tests were conducted on two models of single screw anchors with different geometry to study the effect of embedded depth and blade diameter on anti uplift capacity of the anchor.A theoretical model was developed to predict the ultimate anti uplift capacity of the single screw anchors,the results of which were in good agreement with experimental results. |
