The Bearing Capacity of Footings near Slope Considering the Footing-Soil Interaction
In some cases, structures are built on or near a slope. The ultimate bearing capacity of the foundations for these structures is significantly affected by the presence of the slope. In this paper, the ultimate bearing capacity of footings near slopes is investigated by the finite element method. Consideration is given to the effect of slope angle, height of slope, the distance from the edge of the slope to the footing, soil properties and the interaction between the soil and footing. Conclusions are drawn: In general, the dimensionless bearing capacity qu/γB increases with the increase of the ratio cu/γB, the increase of L/B, and decrease of the slope angle β. The curves describing the relationship between cu/γB and qu/γB can be characterized using three main properties, namely a linear section, a non-linear section, and zero bearing capacity point. Within the linear section, local bearing capacity failure contained to within the face of the slope; the height of the slope does not influence the bearing capacity. In the non-linear section, the curves of the relation (cu/γB, qu/γB) is governed by overall slope failure.
