Resumo: | The dam construction tecnology with roller compacted concrete has undergone noticeable improvements in the areas of concrete technology and enforcement procedure. One can cite the enrichment of roller compacted concrete dam face and the whole sequence leading to obtaining such enrichment, in a short-term enforcement, by the least cost and with the guarantee of the security needed, as one of those remarkable improvements. This work, however, tries to contribute with the theme of the properties of concrete and incorporates basic issues of materials science to set a failure criterion to the results of combined loadings tests performed in RCC specimens of varied sizes, made with the same dosage of Junqueira et al. (2008). The goal is to predict the real strength of the roller compacted concrete dam. Therefore, tests of diametral compression, uniaxial compression, triaxial compression and direct shear tests were performed in RCC specimens of different sizes. The results of such tests were presented using tables and graphs which showed a fall of resistance with increasing the size of the specimen tested face of such loadings. Finally, the data from all trials of this work and of Junqueira et al. (2008) were gathered and studied, so as to increase the precision of the strength envelope of Hoek and Brown set. |

Pode-se citar o enriquecimento do concreto compactado com rolo de face de barragens e toda a seqüência que leva à obtenção de tal enriquecimento, a um curto prazo executivo, pelo menor custo e com a garantia da segurança necessária, como uma dessas notáveis melhorias. O presente trabalho, no entanto, tenta contribuir com o tema das propriedades do concreto e retoma questões básicas da ciência dos materiais para ajustar um critério de ruptura aos resultados de ensaios sob carregamentos combinados realizados em corpos de prova de Concreto Compactado com Rolo (CCR) de dimensões variadas, feitos de dosagem semelhante à usada no trabalho de Junqueira et al. (2008). O objetivo é tentar prever a resistência real apresentada pelo CCR no interior do corpo de uma barragem. Para tanto, foram realizados ensaios de tração na compressão diametral, compressão simples, compressão triaxial e de cisalhamento direto em corpos-de-prova de CCR de dimensões variadas. Os resultados de tais ensaios foram apresentados por meio de tabelas e gráficos os quais mostraram uma queda de resistência com o aumento das dimensões dos corpos de prova ensaiados frente a tais carregamentos. Por fim, os dados de todos os ensaios realizados durante a presente pesquisa e durante a pesquisa de Junqueira et al. (2008) foram agrupados e estudados, a fim de se aumentar a precisão do ajuste da envoltória de resistência de Hoek e Brown.Submitted by Leandro Machado (leandromachado@ufg.br) on 2022-12-21T17:35:40Z No. of bitstreams: 2 Dissertação - Pedro João Barbosa Junqueira - 2010.pdf: 13417648 bytes, checksum: a46909c4f659388d007bcce3962156c3 (MD5) license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5)Rejected by Luciana Ferreira (lucgeral@gmail.com), reason: Falta o link do lattes do aluno e do co-orientador, ambos possuem lattes.
