Abstract(s)
Na presente investigação pretendeu-se definir a espessura das camadas e superfície de bed-rock através dos ensaios de refração sísmica e do PDM (Penetrómetro dinâmico médio). Os resultados destes dois ensaios foram comparados entre si de forma a verificar qual o melhor para o caso de estudo para no fim se fazer um cruzamento de dados. Quando obtidos estes resultados, posteriormente realizaram-se perfis e superfícies 3D do firme para uma melhor interpretação visual dos resultados. Para esta pesquisa foi escolhido um campo de testes localizado na FEUP, no qual se sabe que é um terreno remexido onde foi enterrada sucata. Do resultado desta investigação evidenciou-se algumas das vantagens e desvantagens destes métodos assim como se conclui que apesar de métodos diferentes, é possível verificar que muitos dos resultados obtidos pela sísmica, no que diz respeito as espessuras de camadas superficiais, conseguem ser comprovados pelo ensaio de penetrómetro dinâmico médio (PDM) e vice-versa.
In the current investigation the main purpose was to define the thickness of the layers and the deepness of the bed-rock by the seismic refraction method and the dynamic penetrometer medium method. The results of both methods were compared to each other to verify what method should be used for the purpose in study and in the end make result crossover. After the obtained data, profile and 3D surface was built for a better visual interpretation of the data. For this investigation, the field test located in FEUP (Porto) was chosen, in which it is known that it is a field where was buried scrap. The result investigation, it was evident some of the advantages and disadvantages of each method as was concluded that despite being different methods was possible to verify that many of the results obtained in the seismic refraction method, regarding the thickness of the layers, can be proven by the dynamic penetrometer medium (DPM).
