This paper presents an analytical approach to determine the ultimate load-bearing capacity of a footing subjected to a vertical load and resting on the top of a fly ash slope without or with single or multi-layers geogrid reinforcement. The load-bearing capacity values obtained by using the proposed analytical approach were compared with those obtained from experimental and numerical approaches reported recently in the literature. After validation of the analytical values of the load bearing capacity, an empirical formula based on a regression analysis was developed between the bearing capacity ratio and geogrid index (α), which physically signifies the mobilized strength of geogrid reinforcement under a given footing load and is a function of the number of reinforcement layers (N) and the embedment ratio (z/B).
