Resumo
Esta pesquisa apresenta o dimensionamento de um muro de contenção do tipo gabião com base na caracterização geotécnica de um solo residual na cidade de Biguaçu/SC. A descrição física do solo foi obtida através dos resultados de ensaios de granulometria, densidade real dos grãos, limites de liquidez e plasticidade, compactação. A caracterização mecânica embasou-se a partir dos ensaios de expansão, determinação do CBR e cisalhamento direto. O solo residual foi classificado como um silte argiloso, desuniforme, mal graduado e altamente plástico. A modelagem do talude, muro de gabião e análises de estabilidade foram feitas por meio do software GEO5 da Fine Softwares. Foram apresentadas seis propostas de geometria para o muro de gabião, mas apenas três delas obtiveram resultados satisfatórios quanto a estabilidade interna, global e fundação. Conclui-se que a geometria 1 foi a estrutura que obteve o menor volume de construção conjunto a fatores de segurança satisfatórios.
This research presents the sizing of a gabion-type retaining wall based on the geotechnical characterization of a residual soil in the city of Biguaçu/SC. The physical description of the soil was obtained through the results of granulometric tests, real grain density, liquidity and plasticity limits, compaction. The mechanical characterization was based on expansion tests, determination of CBR and direct shear. The residual soil was classified as clayey, uneven, poorly graded and highly plastic soil. Glacis modeling, gabion wall and stability analysis were performed using Fine Softwares GEO5 software. Six geometry proposals for the gabion wall were presented, but only three of them obtained satisfactory results in terms of internal and global stability and foundation. It is concluded that geometry 1 was the structure that obtained the smallest construction volume with satisfactory safety factors.
