Desempenho de uma barragem de terra e enrocamento com base nos dados da instrumentação geotécnica após 10 anos da construção. estudo de caso: a barragem de uma UHE no interior de Minas Gerais

Abstract

This study had as main theme the analysis of the performance of a dam of earth and rock formation based on the data of the installed geotechnical instrumentation, after 10 years of its construction and filling of the reservoir. Firstly, a literature review was carried out with the intention to base the study, to review the theoretical basis of soil behavior, geotechnical parameters and design criteria for dam stability, as well as the types of auscultation instruments for geotechnical monitoring. After the literature review, a case study of a hydroelectric dam located in the state of Minas Gerais was performed and its stability analysis was performed based on the data of the instruments, concluding that the dam presents behavior within the safety criteria and according to project.
