Resumo: The foundation of the Jaburu I dam it is a classical performance case of foundations in sandstone sedimentary rock. The continuous monitoring of the dam has been the detected the non-regular seepages and adopted in establishing the planning and execution of the remediation campaigns in way to keep the foundation and damâs structures in safety conditions over three decades of operation, in despite of the ineffectiveness of conventional treatment foundation in sedimentary formation that had been used. Seepage anomalies indentified since the first filling of the reservoir in some regions of embankment and its foundation, detaching a significant flow in the left abutment which reached the maxima discharge of 47 l / s in 1988. Since then new points of resurgences have been identified and monitored by flow gages located in the downstream region. This monograph presents the events recorded in the flow gages and the remedial campaigns adopted to reduce the seepage in the foundation, embankment and abutments of the dam, as well as others specific interventions designed to recover the internal drain, stabilize the dam and to fill the cavities formed by the decomposition of the sandstone rock in the foundation. After the publication of the Law 12.334/2010, which established the National Policy of Dam Safety, it was established a complete list of responsibilities related to the safety of dams in Brazil, some of them already taken as routine by the Government of Cearà since 2002. This monograph recommends to the rock foundations of the dam, treatments with new sealing technologies that would mitigate the present anomalies.

A fundaÃÃo da Barragem Jaburu I apresenta comportamento clÃssico em se tratando de fundaÃÃes em rocha sedimentar tipo arenÃtico. O monitoramento contÃnuo deste empreendimento tem sido o principal indicador no estabelecimento do planejamento e execuÃÃo das aÃÃes de tratamento das fundaÃÃes e recuperaÃÃo das estruturas comprometidas no decorrer de trÃs dÃcadas, onde se pode verificar a pouca eficÃcia do tratamento convencional de fundaÃÃo em ambiente sedimentar. Desde o primeiro enchimento do reservatÃrio foram identificadas anomalias no maciÃo de terra e na fundaÃÃo, em forma de percolaÃÃo, juntando-se a estas uma significativa vazÃo na ombreira esquerda que alcanÃou um pico de 47 l/s, em 1988. Desde esta ocasiÃo, novos pontos de surgÃncias foram identificados e monitorados por meio de medidores de vazÃo na regiÃo de jusante. Apresentase, assim, os acontecimentos registrados na barragem e os programas de tratamentos adotados para reduzir as percolaÃÃes pela fundaÃÃo, do corpo da barragem e ombreiras, assim como outras intervenÃÃes realizadas com o propÃsito de drenar o fluxo, estabilizar a barragem e obturar as cavidades provenientes da decomposiÃÃo da rocha arenÃtica.
