Undrained bearing capacity of surface footings near slopes

V. Q. Nguyen and R. S. Merifield

Abstract

In this paper, finite element analysis is used to investigate ultimate undrained bearing capacity of surface footings near slopes. 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. There are two possible collapse modes for a footing located near a slope, namely due to overall slope stability or bearing capacity failure. Both of these failure modes are affected not only by the footing load but also by the soil body forces.
