Abstract

This paper presents a numerical analysis of the centric loading of a strip footing on a cohesive slope. This paper investigates the influence of slope geometry (β), soil strength (Cu), normalized footing distances (λ), and an embedded depth ratio on bearing capacity (Dƒ/B). These factors are compared with the previous literature. It is evident from the results that slope geometry (β), soil strength (Cu), normalized footing distances (λ), and embedded depth ratio (Dƒ/B) have significant effects on undrained bearing capacity. The slope creates an unfavorable effect on bearing capacity by reducing the resistance in the passive wedge. Compared to shallow foundations, deeply installed foundations have a much higher ultimate bearing capacity.
