| Rapid urbanization near the mountainous areas and sloping grounds and its effect on bearing capacity of shallow foundations have become one of the foremost geotechnical challenges in some regions. Bearing capacity of a strip foundation adjacent to a slope depends on many factors including slope angle (β), inclined load angle (θ), soil friction angle (φ), slope height (H), distance of the edge of foundation from the slope (λ) and depth of the foundation (D). Although there have been many studies on these parameters in recent years, the effect of the mentioned parameters on bearing capacity of shallow foundations and simultaneously under the inclined load effect is still not investigated. In this concept and by modeling foundation and sloping ground in ABAQUS 6.14.1, the bearing capacity of shallow foundation underlaid by drained sandy soil and under the effect of the inclined load and the mentioned parameters is studied. The results show that by increasing slope angle and slope height, the bearing capacity of the adjacent strip foundation decreases. Also, by increasing the distance of the edge of foundation from the slope and the load angle, the bearing capacity of the adjacent strip foundation increases. Numerical studies show that the effective distance of the slope on the bearing capacity of adjacent strip foundation is about 4B (B represents the width of strip foundation). In this article, the results of the current study are compared with the studies of the other researchers in cohesive and granular soils. The results show that by taking into account the concurrent effect of all the parameters in design, the effect of slope angle on the bearing capacity of shallow foundation should be significantly noticed. | ||
