In order to investigate the pullout resistance of the Horizontal-Vertical reinforcement, a 'denti-geogrid' was assembled by bonding a 'denti-strip' with the geogrid and the pullout tests were carried out. Subsequently, the analytical approaches were investigated to calculate the pullout resistance on the basis of the surface sliding model, Perterson and Anderson’s model, Jewell’s model, Chai’s model, and the proposed stress summation model. Moreover, a new index named 'scale factor' was suggested to reflect the proportion of bearing resistan...
