Bearing Capacity of an Eccentrically Loaded Strip Footing on Reinforced Sand Slope

Abstract

This paper presents the results of experimental tests undertaken to investigate the effect of the slope 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 results obtained are presented in the form of a parametric study in order to examine the effect of the slope on the bearing capacity 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 load eccentricity located far away from the slope face compared to that of a load eccentricity located towards the slope face. The results also indicate that the behavior of an eccentrically loaded footing on a reinforced sand slope is different compared to that built on a horizontal base.
