THE EFFECT OF GEOGRID REINFORCEMENT ON PULLOUT PARAMETERS OF SAND: EXPERIMENTAL INVESTIGATION AND ANALYSIS

Geogrid reinforcement is a commonly used technique to improve the stability of soil structures. In this study, we investigate the effect of geogrid reinforcement on the pullout parameters of sand through experimental methods. Pullout tests were conducted on sand samples with and without geogrid reinforcement using a custom-built pullout apparatus. The results showed that the geogrid reinforcement significantly increased the pullout force and displacement of the sand, and the pullout parameters, such as the interface friction angle, peak shear stress, and ultimate tensile strength, were also found to be higher for the geogrid-reinforced sand. The findings of this study can provide useful information for designing and constructing geogrid-reinforced soil structures.
