This paper presents the results of experimental and numerical tests undertaken to investigate the slope effect on the bearing capacity of an eccentrically loaded strip footing on a geogrid reinforced sand slope. Several tests were conducted on a reduced model footing under various eccentric loads. The obtained results are presented in the form of a parametric study in order to examine the effect of the slope on the bearing capacity and the depth (µ) of the geogrid layers of the footing under different eccentric loads. This study showed that the location of the load eccentricity relative to the slope crest has a significant effect on the foundation behavior. The bearing capacity is higher in the case of an eccentrically load located far away from the slope face compared to that of an eccentrically load located towards the slope face. It also showed that the behavior of an eccentrically loaded footing on a reinforced sand slope is different compared to that established on a horizontal ground.
