RESUMO

The main objective of this research is the application of the finite element method (FEM) to analyze the stability of soil slopes, searching the position of the failure slip surface in the soil mass and its corresponding safety factor. The finite element method has become a popular tool for the study of many geotechnical engineering problems but, in the specific area of slope stability analysis, there are relatively few applications reported in the literature. Basically, two methods have evolved for application of the FEM results in slope stability problems: the direct method, that uses the numerical results only for establishing the slip surface and computation of the related safety factor, and the indirect method, where the FEM results are combined with another numerical technique to improve the search process of slip surfaces. Several numerical examples have been studied in this dissertation, making comparisons among the results obtained using the finite element and limit equilibrium methods. The applicability, advantages and shortcomings of both approaches are also discussed.
