Abstract(s)
A presente dissertação aborda no âmbito da instabilidade de vertentes, a análise das principais implicações na construção de infra-estruturas rodoviárias na zona da Pontinha em Machico, no sentido de perceber e valorizar a importância que estes movimentos de vertente têm na escolha de soluções de projecto e de execução da obra.
Serão abordadas as características geotécnicas dos solos que formam o vale de Machico, e a análise da tipologia dos movimentos de vertente, estes processos são a principal causa de danos provocados em infra-estruturas no concelho.
Serão também apresentados extensivamente as principais patologias que surgiram nas várias infra-estruturas vizinhas á construção da rede rodoviária, provocadas por movimentos de vertente, fundamentalmente habitações.
Finalmente, vão ser apresentadas várias soluções e técnicas para melhorar o comportamento deste tipo de solos, e serão apresentadas algumas medidas de estabilização e tratamento de solos.
The present dissertation boards in the context of the instability of slopes, the analysis of the principal implications in the construction of road infrastructures in the zone of a Little bit in Machico, in sense of realizing and valuing the importance that has these movements of slope in the choice of solutions of project and of execution of the work. The characteristics will be boarded geotécnicas of the grounds that form the valley of Machico, and the analysis of the tipologia of the movements of slope, that are the principal cause of damages provoked in infrastructures in the district. There will be presented also extensively the principal pathologies that appeared in the newspaper commentaries nearby infrastructures á construction of the road net, provoked by movements of slope, fundamentally dwellings. Finally, several solutions and techniques are going to be introduced to improve the behaviour of this type of grounds, and there will be presented some measures of stabilization and treatment of grounds.
