The performance of foundations located adjacent to natural slopes continues to pose significant technical challenges in geotechnical engineering, attributed to compromised soil stability, reduced bearing capacity, and increased foundation settlement. These phenomena are especially pronounced for ring foundations, which are adopted extensively for axi-symmetric superstructures such as silos, oil tanks, chimneys, and wind turbines. PLAXIS 3D software was used for numerical analysis. Some of the most critical parameters studied are the effect of soil properties and the differential settlement between two different regions on the ring foundation. The internal stress responses of the foundation structure, including the distribution of shear force and bending moment, are also studied. Important soil properties, including the friction angle and elastic modulus, exert comparable influences on foundation performance. The research reveals differential settlement between nodes situated nearest the slope and those positioned farther away. The resultant of bending and shearing forces in the ring foundation is proven to be most greatly influenced by slope geometry. The results are essential for the foundation of modern construction. The data will lead to the development of resilient designs for ring foundations on slopes.
