Resumo: | A dam is a structure built across a valley whose function is to contain water or waste from a production process. This study aimed to gather information about the construction of earth and earth dams with rockfill to contain mining and water tailings, with emphasis on the most common raising construction models in Brazil. In this sense, a literature review was conducted based on qualitative descriptive research focusing on bibliographic materials that study the constructive issues of the heightening of this type of work. These constructions have three executive methods for the containment of tailings, one of raising downstream, upstream and at the center line, and one, the one-off raising, for the damming of water. Both must follow the criteria established for the construction of the earth or rock mass, using suitable materials, and carrying out the compaction with monitoring of laboratory tests, to ensure that the landfill has good structural performance. Furthermore, it is extremely important to design the external drainage system to avoid soil erosion around the building and to prevent disasters. The main causes of dam failure include the absence of continuous monitoring, austere control during its construction/operation and deficiency of the drainage system. It was found, therefore, that to make the appropriate choice of the constructive model of the dam heightening, its purpose must be analyzed, in addition to carrying out continuous monitoring and, if necessary, decommissioning, deactivation or de-characterization. |

Este estudio tuvo como objetivo recopilar información sobre la construcción de presas de tierra y tierra con escollera para contener relaves mineros y de agua, con énfasis en los modelos de construcción de elevaciones más comunes en Brasil. En este sentido, se realizó una revisión bibliográfica a partir de una investigación descriptiva cualitativa centrada en materiales bibliográficos que estudian las cuestiones constructivas del realce de este tipo de obras. Estas construcciones cuentan con tres métodos ejecutivos para la contención de relaves, uno de levantamiento aguas abajo, aguas arriba y en la línea de crujía, y uno, el de levantamiento, para el embalse de agua. Ambos deberán seguir los criterios establecidos para la construcción del macizo de tierra o roca, utilizando materiales adecuados y realizando la compactación con seguimiento de pruebas de laboratorio, a fin de asegurar que el relleno sanitario tenga un buen comportamiento estructural. Además, es extremadamente importante diseñar el sistema de drenaje externo para evitar la erosión del suelo alrededor del edificio y prevenir desastres. Las principales causas de la falla de las represas incluyen la falta de monitoreo continuo, un control estricto durante la construcción/operación y la deficiencia del sistema de drenaje. Se constató, por tanto, que para realizar la elección adecuada del modelo constructivo del recrecimiento de la presa, se debe analizar su finalidad, además de realizar un seguimiento continuo y, en su caso, el desmantelamiento, desactivación o descaracterización.Uma barragem é uma estrutura construída transversalmente a um vale cuja função é a contenção de água ou de resíduos provenientes de um processo produtivo. Este estudo teve como objetivo reunir informações sobre a construção de barragens de terra e de terra com enrocamento para contenção de rejeitos de mineração e de água, com ênfase nos modelos construtivos de alteamentos mais comuns no Brasil. Neste sentido, foi conduzida uma revisão de literatura a partir de uma pesquisa descritiva qualitativa com foco em materiais bibliográficos que estudam as questões construtivas do alteamento deste tipo de obra. Essas construções possuem três métodos executivos para a contenção de rejeitos, o de alteamento à jusante, à montante e à linha de centro, e um, o de alteamento único, para represamento de água. Ambos devem seguir os critérios estabelecidos para a construção do maciço terroso ou rochoso, utilizando materiais adequados e executando a compactação com acompanhamento de ensaios laboratoriais, de forma a garantir que o aterro tenha bom desempenho estrutural. Além do mais é de extrema importância o dimensionamento do sistema externo de drenagem, para evitar a erosão do solo no entorno da construção e prevenir desastres. As principais causas para rompimento de barragens incluem, ausência de monitoramento contínuo, controle austero durante sua construção/operação e deficiência do sistema de drenagem. Constatou-se, portanto, que para realizar a escolha apropriada do modelo construtivo do alteamento da barragem deve-se analisar a sua finalidade, além de efetuar o monitoramento contínuo e se necessário o descomissionamento, desativação ou descaracterização.Research, Society and Development2022-08-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3346910.33448/rsd-v11i11.33469Research, Society and Development; Vol. 11 No. 11; e277111133469Research, Society and Development; Vol. 11 Núm. 11; e277111133469Research, Society and Development; v. 11 n. 11; e2771111334692525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/33469/28429Copyright (c) 2022 Daniele Cristina Lopes Mariano; Juliana Braga Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMariano, Daniele Cristina Lopes Silva, Juliana Braga 2022-09-05T13:24:46Zoai:ojs.pkp.sfu.ca:article/33469Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:49:06.392032Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
