Abstract

In this research, pull-out experiments of model flip-type ground anchors (flip anchor, hereafter) were conducted in two-dimensional (plane strain) condition to investigate the fundamental pullout mechanisms of flip-type ground anchor. A transparent acrylic soil box was used as a soil box. Rectangular model flip anchors had the depth of 98 mm, and breadths, B, of 48 mm or 80 mm, so that the depths of the soil box and the model anchors were the same. The anchor was buried in the dry sand model ground and pulled-out. The experiments were carried out by changing embedment depth, h, initial positions of the anchor head (open or closed), and width of anchor head, B. Pull-out force, F, and pull-out displacement, w, were measured. The ground movements were observed using a PIV analysis. Based on the image analyses, ground failure pattern was simply modelled. The model simulated the tendency of the experimental values well. It would be expanded to three-dimension to design actual flip-type anchors.
