GRAVITY-INDUCED STRESSES IN FINITE SLOPES

An exact solution for gravity-induced stresses in finite elastic slopes is presented. This solution, which is applied for gravity- induced stresses in 15, 30, 45 and 90 degree finite slopes, has application in pit-slope design, compares favorably with published finite element results for this problem and satisfies the conditions that shear and normal stresses vanish on the ground surface. The solution predicts that horizontal stresses are compressive along the top of the slopes (zero in the case of the 90 degree slope) and tensile away from the bottom of the slopes, effects which are casued by downward movement and near-surface horizontal extension in front of the slope in response to gravity loading caused by the additional material associated with the finite slope.
