ABSTRACT

An approximate analysis for stress and failure of earth slopes is proposed. To simulate the stress variation along the slope, elastic stress influence from the presumable uplift pressure acting on a level ground is superimposed to the stress state of the ground. Stability condition of the slope is verified by comparing the mobilized Mohr’s circle with the presumable failure envelope for material points along the slope. It is found that the stress variation obtained is similar to the previous solutions. The results are closest to other solutions in the case where the Poisson’s ratio is relatively large. The failure potential of the slope obtained is more conservative in comparison with the one from limit equilibrium analysis. The averaged stability of that critical plane from the proposed method is compatible with the conventional solution.

Keywords: slope stability, stress analysis, failure potential.
