In this paper, the bearing capacity of a slope of cohesionless soil under the load acting upon its horizontal top or berm is obtained. The process is similar to the cases of horizontal ground, reported previously by one of the authors.The authors also assume in the present case that at the instant of failure a wedge of active earth pressure would appear directly below the load. A region of passive earth pressure along the slope can be determined as a function of the angle of slope and the angle of internal friction of soil.The transition region between the above-said two parts is divided into a number of small wedges. For these wedges the equilibrium condition of force is applied successively and at the same time the sliding surface is drawn by taking into account the sliding condition, the stress components being found by means of Mohr's circle. And thus the bearing capacity can be determined.
