The structural behavior of footings in sloped terrains is a critical concern in geotechnical engineering. Over 15% of India’s total geographical area is made up of hilly regions, the majority of which have slopes. Because of geographical limitations, such as in the case of retaining walls and bridge abutments, or for architectural reasons, structures may be built on or near slopes. The presence of a slope has a substantial bearing capacity impact on foundations built on or next to slopes. Under these circumstances, the foundation’s design is complicated, and there is little information in the literature. A finite element analysis (FEA) approach is employed to model the complex interactions between the footing, layered slope, and the applied loads. This research presents a comprehensive numerical study aimed at understanding the response of square footing situated in a layered reinforced slope under the combined effect of eccentric and inclined loading. Two cases were considered: unreinforced sand slope and reinforced slope by geogrid at the interface of the layered soil. The numerical model includes several parameters, including the distance between the footing and the top of the slope, different slope angles, and the inclusion of reinforcement. The bearing capacity of square footing reduces under the effect of inclined and eccentric loading. The location of a footing with respect to the slope and slope inclination has significantly reduced the slope’s stability and the soil’s bearing capacity when it is located adjacent to the crest of a sloping surface. Settlement increases and bearing capacity decreases with an increase in slope angle. However, with the inclusion of a reinforcement layer, the bearing capacity is enhanced significantly.
