Abstract(s)
O presente Trabalho Final de Mestrado refere-se à realização de um estágio curricular, com uma duração de 4 meses, no Departamento de Infraestruturas e Transportes da empresa SENER-ENGIVIA - Consultores de Engenharia, S.A., no âmbito do Mestrado em Engenharia Civil, área de especialização de Vias de Comunicação e Transportes, do Instituto Superior de Engenharia de Lisboa.
No Estágio foi possível colaborar em diferentes tipos de projetos de infraestruturas rodoviárias e aeroportuárias, assim como na participação de um concurso público internacional para a construção de uma empreitada rodoviária.
Das várias atividades desenvolvidas durante o período de Estágio, destaca-se o acompanhamento de um projeto internacional de uma infraestrutura rodoviária “Duplicação, melhoria e ampliação da capacidade e segurança da Rodovia BR - 381 / MG” de um troço de 29 km, em Minas Gerais, no Brasil. Este projeto suscitou bastante interesse, não só por ser um projeto a nível internacional, mas também pelo facto de serem tratados diferentes tipos de intervenção associados a uma estrada existente. Através desta colaboração surgiu o Caso de Estudo, que suporta o tema do Trabalho Final de Mestrado, proporcionando a análise da geometria de traçado e a comparação entre as Normas Portuguesas e Brasileiras.
Esta análise comparativa entre as Normas é realizada no Caso de Estudo através de 2 trechos da referida Rodovia BR - 381, de modo a possibilitar uma aplicação efetiva dos respetivos documentos Normativos. O primeiro trecho refere-se a uma zona onde irá ocorrer a duplicação da estrada existente e o segundo trecho corresponde à construção de uma nova faixa de rodagem.
Com este estudo, pretende-se otimizar as soluções de traçado, dando a conhecer não só as diferenças resultantes da aplicação de cada uma das Normas, mas também o que poderia ser melhorado em termos de conceção de traçado, e em particular no que se refere à segurança rodoviária, caso fosse possível a conjugação dos critérios das Normas de cada um dos países.
The current Master’s Final Project refers to the realization of a curricular internship, with a duration of 4 months in the Department of Infrastructures and Transports, in the company SENER-ENGIVIA, Consultores de Engenharia, S.A., as part of the Master’s degree in Civil Engineering, specialized in the area of Communication Routes and Transports, of the Instituto Superior de Engenharia de Lisboa. In the Internship, I was able to collaborate in different kinds of infrastructure projects: in roads; airport construction field; participate in a public tender for the contract construction of a road. Of all the various conducted activities during the Internship, the monitoring of an international project of a road infrastructure “Duplication, improvement and expansion of the capacity and security of the Highway BR-381 / MG “of a 29 km section’s, in Minas Gerais, Brazil. This fact has raised quite an interest, not only for being an international project, but also for the fact that various kinds of interventions were being arranged, associated to an already existing road. Through this collaboration, a case study emerged which will be used as support to the Master’s Final Project, in other words, it will be the comparison basis for the analysis of the laid out geometry of the Portuguese and Brazilian Regulations. This comparative analyses between Regulations is accompanied by the case study of 2 segments of the previous referred Road BR-381 in order to allow an effective application of the respective regulation documents. The first segment will represent one zone where the duplication of the existent road will occur and the second segment corresponds to a new traffic lane that will be constructed. With this study, the purpose is to conduct an optimization of the layout solutions, setting out not only the resulting layout differences of the application of each Regulation, but also what could be improved in terms of layout design and in particular road safety, if it was possible the combination of each country’s Regulation criterias.
