Ultimate Bearing Capacity near Slopes: Transition from a Bearing Capacity Problem to a Slope Stability Problem
Evaluating the bearing capacity adjacent or near slopes is an important issue as it effects design criteria not only for shallow foundations, but walls and highway structures. Past research has evaluated bearing capacity near slopes often using analytical models using a projected, two-sided failure mechanism that is based on punching or shear failure of strip footings; however, the failure mechanism for bearing capacity may transition into a one-sided slope failure when the influence of the slope is significant. This analysis evaluates both bearing capacity near slopes and coupled slope failure using a parallelized limit equilibrium procedure, evaluating not only the ultimate bearing capacity, but also the associated mechanism for failure. The proposed model is verified against both known bearing capacity equations for horizontal ground, but also compared to numerical analyses, showing good agreement. A subsequent parametric analysis is performed to evaluate the effects of slope angle, setback and friction angle of soil, presented in convenient design charts.
