Available in PDF, EPUB and Kindle. Book excerpt: O conhecimento do comportamento de solos residuais é de grande importância para projetos geotécnicos no Brasil e, em particular, na região do Rio de Janeiro, tendo em vista que o clima tropical e as características geológicas favorecem a ocorrência de mantos residuais de grande espessura. O presente trabalho trata do estudo do comportamento tensão-deformação de um solo residual proveniente de um perfil de alteração de rocha gnáissica do maciço da Tijuca, Rio de Janeiro. Como os solos residuais gnáissicos preservam as foliações herdadas da rocha matriz, investigou-se em particular a relevância de se considerar a ocorrência de anisotropia nas características de resistência e deformabilidade destes solos. No estudo foi utilizado o equipamento triaxial cúbico desenvolvido na PUC-Rio. Este equipamento possibilita o controle independente das três tensões principais, sendo mais adequado para a reprodução das trajetórias de tensões tridimensionais, usualmente associadas com obras geotécnicas no campo, e em particular, para estudos sobre as características de anisotropia de solos. O programa experimental constou de ensaios de compressão axial e hidrostática, sob condições drenadas de carregamento, utilizando o equipamento triaxial cúbico. Foram realizados também ensaios oedométricos convencionais, de modo a se obter as características de compressibilidade do solo. Foram moldados corpos de prova a partir de blocos indeformados, paralelos e perpendiculares à foliação observada no solo, o que possibilitou a análise dos resultados para direções distintas de carregamento. Para efeito de comparação sobre a relevância do arranjo estrutural dos grãos do solo, foram ensaiados também corpos de prova compactados dos mesmos materiais. A análise dos resultados permitiu a obtenção dos módulos de deformabilidade e dos parâmetros de resistência do solo residual. Em particular, foram verificados os efeitos da direção de carregamento dos corpos de prova, do nível das tensões de confinamento, do grau de intemperismo, do arranjo estrutural dos grãos e dos efeitos do grau de saturação. Pode-se concluir que os solos estudados não apresentaram efeitos marcantes de anisotropia nas características de resistência. No entanto, quanto à deformabilidade, pode-se considerar que o solo residual jovem apresentou características anisotrópicas.

Available in PDF, EPUB and Kindle. Book excerpt: O presente trabalho consiste num estudo experimental de laboratório, no qual procurou-se analisar o comportamento tensão-deformação-resistência de um solo residual jovem de biotita gnaisse na condição saturada. Foram realizados ensaios de compressão isotrópica e edométrico através dos quais foi definida a tensão de pré-adensamento do solo em estudo. Posteriormente foram realizados ensaios triaxiais de compressão e extensão seguindo diferentes trajetórias de tensão, com autilização de instrumentação interna (ELETRONÍVEIS) para medição das deformações axiais. A utilização dos ELETRONÍVEIS possibilitou a identificação de uma superfície de escoamento no espaço de tensões de compressão e de extensão. Foi analisado o módulo secante de deformabilidade obtido com o uso do LSCDT e dos ELETRONÍVEIS a partir dos ensaios triaxiais. O estudo microestrutural do solo feito através de lâminas delgadas, analisadas ao microscópio óptico e eletrônico de varredura, possibilitou a verificação de cimentação entre os grãos do solo. Esta é causada pela cimentação do ferro liberado através da intemperização dos minerais de granada e biotita.

Book Synopsis Rock Mechanics by : Barry H.G. Brady
Download or read book Rock Mechanics written by Barry H.G. Brady and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition has been completely revised to reflect the notable innovations in mining engineering and the remarkable developments in the science of rock mechanics and the practice of rock angineering taht have taken place over the last two decades. Although "Rock Mechanics for Underground Mining" addresses many of the rock mechanics issues that arise in underground mining engineering, it is not a text exclusively for mining applications. Based on extensive professional research and teaching experience, this book will provide an authoratative and comprehensive text for final year undergraduates and commencing postgraduate stydents. For profesional practitioners, not only will it be of interests to mining and geological engineers, but also to civil engineers, structural mining geologists and geophysicists as a standard work for professional reference purposes.

Book Synopsis Geotechnical Engineering by : V.N.S. Murthy
Download or read book Geotechnical Engineering written by V.N.S. Murthy and published by CRC Press. This book was released on 2002-10-25 with total page 1066 pages. Available in PDF, EPUB and Kindle. Book excerpt: A must have reference for any engineer involved with foundations, piers, and retaining walls, this remarkably comprehensive volume illustrates soil characteristic concepts with examples that detail a wealth of practical considerations, It covers the latest developments in the design of drilled pier foundations and mechanically stabilized earth retaining wall and explores a pioneering approach for predicting the nonlinear behavior of laterally loaded long vertical and batter piles. As complete and authoritative as any volume on the subject, it discusses soil formation, index properties, and classification; soil permeability, seepage, and the effect of water on stress conditions; stresses due to surface loads; soil compressibility and consolidation; and shear strength characteristics of soils. While this book is a valuable teaching text for advanced students, it is one that the practicing engineer will continually be taking off the shelf long after school lets out. Just the quick reference it affords to a huge range of tests and the appendices filled with essential data, makes it an essential addition to an civil engineering library.
