Previous issue date: 2014-12-19 / A solu??o da equa??o diferencial parcial de problemas de percola??o ? dif?cil
de ser encontrada analiticamente, especialmente para situa??es que envolvem
grande complexidade. 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
