This paper investigated the pullout behaviour of shallow vertical plate anchors in sand. Pull-out model tests were performed using the particle image velocimetry (PIV) technology, by which the soil deformation and failure mechanisms were observed. Then the ultimate bearing capacity of vertical plate anchors at various soil properties and cover depths was simulated using the finite element limit analysis software. According to the observed failure mechanism, a limit equilibrium solution was developed to calculate the bearing capacity of shallow strip plate anchors in sand, which was then extended for the prediction of the ultimate bearing capacity of rectangle plate anchors by introducing a shape coefficient. Results predicted by the new limit equilibrium solution showed close agreement with those by the lower bound limit analysis solution. The limit equilibrium solution was compared with 51 experimental data, which showed an average of 5% overestimation of the ultimate bearing capacity. This research can provide a theoretical method for the calculation of the ultimate bearing capacity of shallow plate anchors in sand.
