Abstract(s)
O presente trabalho, numa fase inicial, desenvolve-se no sentido de enunciar o tema
engenharia de fundações. Esta é uma área que até há poucas décadas era, em muitos casos,
descurada e pouco desenvolvida. Face ao mesmo entendimento, inicia-se o tema pela sua
própria definição, por opinião de vários autores. Segue-se um explanar da sua importância e da sua influência nas construções, assim como uma passagem histórica da evolução do tema e fatores que o impulsionaram. No processo evolutivo da engenharia de fundações foi notória a
insuficiência de soluções geotécnicas isoladas para o cumprimento das condições de
segurança ou outras. Com isto, passaram a ser executadas não soluções isoladas, mas
miscelâneas de soluções geotécnicas cada vez mais complexas. São apresentados, neste
trabalho, casos de obras notáveis pela quantidade e complexidade das soluções geotécnicas adotadas e que, no seu conjunto, são a base de grandiosas obras.
Numa segunda fase, é efetuado um estudo de um caso de obra (Elevador inclinado da Goldra,
Covilhã) enquadrando-o no tema principal. É feita uma abordagem da obra no sentido de
entender a sua origem e importância para a população, seguindo-se de uma descrição geral
da mesma obra e enquadramento geológico da área de implantação. Caracteriza-se também
geotecnicamente o maciço no qual é fundada a superestrutura com base em ensaios de
prospeção mecânica, realizados “in situ” e também ensaios laboratoriais de caracterização do solo, realizados na Universidade da Beira Interior, com o objetivo de obter os parâmetros de
dimensionamento das estruturas geotécnicas.
Por fim, é efetuada uma avaliação de segurança das soluções geotécnicas adotadas, como elemento isolado e como solução conjunta, utilizando os parâmetros conseguidos a partir da caracterização geotécnica do maciço. São ainda evidenciados alguns aspetos de valorização da obra, nomeadamente, aspetos ambientais e de enquadramento paisagístico.
This work, initially, develops the sense of stating the theme foundation engineering. This is an area which until a few decades ago was, in many cases, neglected and undeveloped. Compared to the same understanding, begins the topic by its own definition, by the opinion of several authors. The following is an explain of its importance and its influence on the buildings, as well as a historical passage of the evolution of the topic and the factors that boosted. In the evolutionary process of foundation engineering was notoriously insufficient geotechnical isolated solutions to meet the safety conditions or other. With this, began to be implemented no isolated solutions, but miscellany of geotechnical solutions increasingly complex. In this paper are presented cases of outstanding works by the amount and complexity of geotechnical solutions adopted and that, on the whole, are the foundation of great works. In a second phase, a study is made of a case of work (Goldra’s inclined elevator, Covilhã) framing it in the main theme. An approach of the work in order to understand their origin and importance for the population, followed by an overview of the same work and geological setting of the area of deployment. It is also characterized geotechnically the massif in which the superstructure is founded on the basis of mechanical tests of exploration carried out "in situ" as well as laboratory testing of soil characterization, performed at the University of Beira Interior, in order to obtain parameters design of geotechnical structures. Finally, is performed a safety assessment of geotechnical solutions adopted, as an isolated element and as a joint solution, using the parameters obtained from the geotechnical characterization of the massif. Some aspects are still evident appreciation of the work, including environmental aspects and landscaped setting.
