Análise de estabilidade do talude de uma barragem utilizando o software Geostudio

Abstract

This study aims to analyze the stability of the slopes of a homogeneous dam built with sand-clay material. For this purpose, numerical simulations were performed using the GeoStudio software. The Minimum Safety Factors were determined in the different phases of the project, allowing the analysis of the methods adopted. The study used the limit equilibrium methods of Bishop, Fellenius and Morgenstern & Price, available in the aforementioned tool. The parameters of the materials of the dam body were defined based on the data provided by the supervisor, referring to the soil of the abutments of the Ribeirão do João Leite dam. The properties of the filter and foundation materials were obtained from the technical literature. In the numerical simulations, parameters such as permeability, natural specific weight, friction angle and cohesion were considered. The section chosen for the study was designed according to the literature, considering the guidelines for a homogeneous earth dam.
