Análise de estabilidade de talude por meio de simulação numérica: elementos finitos

Abstract

The finite element method (FEM) is widely used throughout engineering due the the speed with which results are obtained. It is also used for various purposes in geotenia, however in order to have satisfactory results you need a good post-processing of results. This method is to approximate results by equations between nodes in a mesh that can be calculated using commercial software. In this work we compared the results of a classical method of slope stability (Bishop Method) with a static and dynamic analysis via MEF, and an objective review of conventional and numerical method for this type of analysis. For the calculations we used the ANSYS software and GEOSLOPE. . For the calculations we used the ANSYS software and GEOSLOPE, who presented the results of the safety factors and satisfactory analysis of the stress state. The results are limited by the first relative to the second, because the GEOSLOPE performs just a two-dimensional analysis while the ANSYS results showed threedimensional, a fact that improved spatial understanding of the problem in question. However, compared with the work of ADRIANO (2009), who worked with the same parameters, the two software showed similar results.
