Para contornar este problema usualmente s?o utilizados softwares com base em diferen?as finitas e elementos finitos. A presente disserta??o apresenta a utiliza??o de um software de elementos finitos, o GEO5, para a resolu??o do problema de percola??o numa barragem de se??o bastante complexa, a Barragem Eng. Armando Ribeiro Gon?alves, que no final de sua constru??o sofreu ruptura do talude de montante da barragem central e, depois passou por um processo de reconstru??o e ausculta??o. As an?lises foram realizadas para a condi??o de opera??o do reservat?rio, com fluxo estabelecido. Um modelo num?rico foi elaborado com base nas leituras de n?vel d??gua do reservat?rio e respectivas leituras piezom?tricas como uma proposta para a avalia??o e previs?o do comportamento futuro da barragem em condi??es de fluxo estabelecido. A utiliza??o de modelos constitutivos com o aux?lio de sistemas computacionais traduz-se em uma forma de se prever futuras situa??es de risco de forma que possam ser evitadas / The solution of partial differential equation of seepage problems is difficult to find analytically, especially for situations that involve great complexity. To overcome this problem, software based on finite differences and finite elements are usually used. This work presents the use of a finite element software, the GEO5, to solve the seepage problem at a dam of very complex section, the dam Eng. Armando Ribeiro Gon?alves, which at the end of its construction suffered rupture of the upstream slope at the central dam and then went through a process of reconstruction and auscultation. The analyses were performed for the operating condition of the reservoir, with an established flow. A numerical model was developed based on the level readings of the reservoir water and their piezometric readings as a proposal for the evaluation and future behavior prediction of the dam on established flow conditions. The use of constitutive models with the aid of computer systems is reflected in a way to predict future risk situations so they can be prevented
