Bearing Capacity of Embedded Strip Footing Placed Adjacent to Sandy Soil Slopes
In some infrastructure projects, the strip footing adjacent to the slope is usually constructed at some depth below the ground surface. For practical engineers, estimating the bearing capacity of such footing is one of the challenging tasks. In this paper, the Finite Element Limit Analysis (FELA) is employed to determine rigorous lower and upper bounds for bearing capacity of embedded strip footing resting adjacent to a sand soil slope. The results obtained using FELA are compared with analytical approaches available in the literature. The parametric studies have been performed to examine the effect of slope angle, friction angle of the soil, footing location, and embedded depth of the footing on the bearing capacity. The results indicate that, when the strip footing is built adjacent to the sandy soil slope, the bearing capacity is reduced depending on the location of the footing relative to the crest of the slope. Also, the bearing capacity of the slope increases with the increase in the embedded depth of footing and the soil strength. Whereas, it decreases with an increase in the slope angle. The numerical outcomes are presented in design charts which can be used by the practicing engineers.
