This investigation aims at finding the effective length of geogrid reinforcement layers under circular footing. For this purpose xperimental models were used.The effect of relative density of the sand and the depth of the footing on the effective length of geogrid reinforcement layer was studied. Also the effect of the change in the length of reinforcement layers on the ultimate bearing capacity was investigated. The results show that the length of reinforcement layers to diameter ratio of circular footing increased withdecreasing relative density of the sand and is not affected by the changeof the depth to diameter ratio of circular footing.
