Estudo do comportamento da barragem de Graus

Abstract

As barragens sao de grande importância devido a sustentabilidade que garantem, pois permitem o abastecimento de aguas, a irrigacao, a producao de energia hidroeletrica, controle de cheias, atividades recreativas e navegacao nos rios. Por razoes tecnicas e economicas, em barragens de concreto e comum utilizar agregados da propria zona de localizacao das mesmas. Entretanto, estes agregados podem nao ser os mais recomendaveis, pois sua qualidade e sua composicao influenciam significativamente as possiveis patologias que podem ocorrer ao longo da vida util das estruturas de concreto. Este estudo trata da avaliacao da barragem de Graus, cujas principais manifestacoes patologicas sao problemas expansivos que originaram mudancas dimensionais irreversiveis na sua estrutura. As principais causas dessa patologia sao o ataque sulfatico interno (ASI) somado a um segundo processo expansivo, baseado nas alteracoes visuais, na presenca de fissuras e nos movimentos da barragem.
