... groups of anchor plates show a clear failure at a displacement of about 5% of the anchor width, whereas this value increases to more than 45% for reinforced groups along with a two-fold increase in uplift capacity. The optimum width and length of the geogrid reinforcement for groups of two anchors...

... in the present technical note. The uplift capacity of plates in sand backfill layers is increased by the insertion of 0.5% fibers in the backfilled material. The enhancement of the uplift capacity increases from about 70% for embedment depth/plate diameter ratio (H/D) equal to 1.0 to about 30...
