Comparación de los métodos de equilibrio límite y elementos finitos aplicados a la estabilidad de taludes.

Abstract

In slope engineering it is very important to know which method is most appropriate to solve a problem, due to the uncertainty that this represents a comparison was made between two methods of analysis using support software developed by BENTLEY. The first methodology uses the theory of limit equilibrium and the second, for comparison, finite elements; these two methods are applied in the software "Slope Stability" and "MEF" respectively. We used data from a study previously carried out by the consulting firm PLANISOC, from which the necessary parameters to obtain the exposed models were obtained. Consequently, safety factors were calculated, which varied according to the scenarios, such as static and pseudo-static analysis, with and without inclusion of water table. The results present certain cases with similarities and in others total discordance, but they reveal certain advantages and disadvantages between methodologies.
