Análise da solução de estabilidade de um talude localizado na Rodovia PR-418, Curitiba-PR

Abstract

The present article aims to present and verify the stability of a slope located on Highway PR-418, contour region North, Curitiba PR. The analysis was made initially by a company contracted by the government of Paraná, which made available the study and project for the development of this work. Using the deterministic methods the slope stability evaluation was performed showing that its safety is satisfactory, despite some caveats. In addition to the stability analysis by Rocscience software Slide, the Phase² software of the same company, based on the finite element method, was used to simulate the construction phases of one of the solutions previously defined by the to analyze the deformations in each step, verifying the functionality of the solution. The results obtained by this numerical analysis showed that the expected deformations for the mass are within the limits expected for the work, but with the appearance of a possible instability when analyzed by the finite element method. We conclude that a limit equilibrium analysis associated with a deformation simulation presents more complete data, and bases the chosen solutions, adding greater safety and reliability to the slope stability projects that usually come from adoptions or parameter variability in single cases and with special conditions.
