Tropical residual clays with a highly porous structure react to the stress changes induced by tunneling in such way that surface settlements can be larger than crown-level along tunnel axis. This behavior, which is not readily simulated most numerical analyses, was also observed Paraiso tunnel, built for São Paulo Metro, Brazil. shallow driven through clayey soils sequential method. Detailed results of field monitoring are presented and discussed. 3D finite-element analyses allowed detailed...
A temática das Políticas Públicas Educacionais no Estado do Ceará é uma proposição instigante em pesquisa, haja vista o configurar Ensino Médio (tradicional e integrado) Educação Profissional, como terceiro melhor Índice de Desenvolvimento da Básica (Ideb), com 4,6, sendo a média nacional 4,1. Já Oportunidades Brasileira (Ioeb) 2023, fica destaque, posto apresentar, ao lado São Paulo, 5,5. Ademais destes dados, 31 municípios cearenses se destacam entre os 50 melhores País (Ceará, 2024). No...
In the north-western region of Portugal residual soils from granite are dominant. Their porous cemented structure leads to a complex geotechnical behaviour, quite distinct that transported with similar grain size distribution. The paper describes some studies carried out at an experimental site on which fairly homogeneous saprolitic soil 6m thick was encountered. These included: (i) full-scale load test circular concrete footing (1·20m diameter), under carefully controlled conditions and...
A previous paper studied the stability of soldier-pile walls in clay under vertical loading using upper bound analyses. classical Tresca yield criterion was assumed that analysis. This extends study by considering a tension truncated an numerical analysis problem. It shows assuming zero soil strength has significant influence on values minimum resistance required to ensure stability.
The problem of vertical stability in flexible anchored retaining walls is analyzed and the pattern behavior under conditions poor support described, on basis results from case histories, small-scale tests, numerical modeling. possibility shear stress mobilization soil-to-wall interface concrete soldier–pile discussed. A finite element procedure to model excavations supported by described applied a study. Finite analyses are performed, emphasizing consequences instability due buckling soldier...
The paper corresponds to the Manuel Rocha Lecture delivered by author in October 2009. It is divided into three main parts. Part 1, Practice and Design, summarizes most relevant excavations performed Portugal since 1950s, with emphasis on selected case histories. 2, Design Research, discusses research work original approaches solutions developed for distinct geotechnical conditions found Portugal. 3, Research Perspectives, presents some ideas points considered critical future developments field.
The vertical stability of anchored concrete soldier-pile walls is highly influenced by the complexity interaction between different parts structure, i.e., wall, anchors, and supported soil mass. problem analyzed using upper bound limit analysis through published solutions proposed closed-form equations. A comparison made these equations numerical analyses. An estimate theoretical minimum pile resistance required to avoid excavation collapse presented. Published finite element elastoplastic...
The paper presents a solution executed for the connection of pre-existing metro tunnel made with tunnel-boring machine to structure station constructed by cut-and-cover method. geotechnical conditions site were very difficult: 26 m man-made fill and alluvial soft silty clay loose sands, water level close surface. was completely covered these soils. consisted mainly in extending retaining wall beyond planes portals, order confine stretches adjacent station, creating volume treated soil jet...

O trabalho passa em revista, de forma resumida, o ensino e a investigação Geotecnia nas universidades portuguesas ao longo das últimas 8 décadas. Essa retrospetiva começa na década 1940, qual foram identificadas as primeiras ações significativas. Para período após 2010, no essencial última década, apresenta-se uma análise mais desenvolvida, que identifica graves dificuldades afetam atualmente qualidade da formação geotécnica número engenheiros civis saídos Universidade com essa formação, bem...

The paper corresponds to the Pacheco Silva Lecture delivered by author in September 2014. In first part of text, a general perspective movements induced deep excavations soft soils is outlined. report presented Ralph B. Peck 1969 ISSMFE México conference taken as reference and progress achieved since then control emphasized. It pointed out that such permits very demanding urban scenarios involving one should work towards performance, with regard movements, similar (or even better than)...
Limit state design applied to geotechnical structures requires the selection of characteristic values ground parameters and use partial safety factors. These factors, way that are selected, will govern calculated probability failure structure.
