TÓM TẮT
The stability of footing-on-slope systems is a major concern in geotechnical engineering, particularly in urban areas. To assess the ultimate bearing capacity of an eccentrically inclined loaded footing on a sand slope, a study used the rigid plastic finite element method (RPFEM) and conducted various analyses. The study investigated the impact of soil strength, footing width, and slope geometry on the three dimensional V-H-M limit load space. Additionally, the influence of two eccentric directions and two horizontal load directions on the V-H-M limit load space was examined. Results revealed that positive eccentricity and positive horizontal load improved the bearing capacity of the strip footing on the slope crest. However, the effect on bearing capacity was negligible when the edge distance exceeded a certain threshold value. The study found that the V-H-M limit load space was unique for each soil strength and slope geometry parameter and applicable for various loading paths
