The Bearing Capacity and Failure Mechanism of Foundations near Slope Based on Nondimensional Parameters

Abstract:

The foundation on slope problem is a special case of the very large bearing capacity problem. Researchers have studied the bearing capacity of slopes as such problems arise quite frequently in practice. The aim of this paper is to study the effect that changing the position of an infinitely long strip foundation, from the edge of the slope to a certain distance away, has on the bearing capacity of a slope. The influence of various nondimensional parameters, such as strength ratio, slope height ratio and so on, on the bearing capacity of slope foundation is also analyzed by the finite element method. Conclusions are as follows: as the foundation is moved away from the slope by increasing D/B, there is a change over point from a slope failure mechanism to a flat ground failure mechanism. As the strength ratio increases for a set D/B, there is a considerable change in the shape of the failure surface initially, followed by only minor changes from strength ratio 10 onwards and so on.
