ESTUDO DO FATOR DE SEGURANÇA DE BARRAGEM DE SOLO NO MUNICÍPIO DE ILICÍNEA - MG

Abstract

The stability analysis of a soil dam consists of the calculation of the safety factor due to the risk of slip failure. For this, a bibliographic research of the inherent literature was performed, besides presenting the main dam concepts, including having used three common methods of the slices to determine the safety factor of the massif. Existing types of dams are presented, as well as the design phases, investigations and laboratory tests not carried out in this work. For the purpose of calculation, some of the geotechnical parameters were established through correlations, since during the construction of the dam, no significant tests were performed to calculate the safety factor. The dam studied is located in a rural property in the city of Ilicínea - MG, and its purpose is to dam water for use in irrigation. With the bibliographic basis and with the aid of software, it was possible to determine the safety factor and conclude that the three methods used, presented satisfactory results, meeting the minimum values established by norm, based on the analyzed geotechnical parameters. Another study carried out in this work was the safety factor behavior due to the variation of the friction angle, cohesion and specific dam weight, so it was possible to conclude that these parameters are of great importance for the safety factor calculation. fundamental parameters, whose engineer must know to determine the soil that will be used in the construction of the dam.
