Experimental study of behavior of circular footing on geogrid-reinforced sand

Load tests were carried out with a circular foundation of diameter, B = 100 mm, supported on geogrid-sand reinforced contained in a circular-steel tank with diameter of 600 mm and depth of 450 mm, to determine the increase produced in the bearing capacity by including geogrid layers in the sand. Two...
