Este relatório, intitulado "Comparação de resultados de ensaios in situ para a caracterização de fundações
de edifícios correntes", foi elaborado no âmbito do Mestrado em Geologia, Aplicada e do Ambiente,
ministrado na Faculdade de Ciências da Universidade de Lisboa. O documento resulta de um estágio
curricular de 9 meses, promovido pela mesma instituição em parceria com a empresa Betoteste, Gabinete
de Estudos de Geotecnia, LDA.
O principal objetivo deste estágio foi compilar informações pertinentes ao tema, com foco nas técnicas
mais utilizadas na geotecnia, prospeção geotécnica e tecnologia de fundações. Durante o estágio, houve
a oportunidade de acompanhar diversas obras e intervenções, discutir soluções técnicas, compreender
as dificuldades reais em campo e adquirir experiência profissional na área. O relatório é fundamentado
em conceitos chave sobre os métodos de prospeção geotécnica, essenciais para entender os objetivos
dos ensaios in situ e laboratoriais realizados. Além disso, aborda-se a temática das fundações de edifícios
correntes.
O papel do geólogo, neste contexto, é avaliar as condições do terreno, obtendo parâmetros geotécnicos
através de ensaios diversos, para fornecer informações detalhadas sobre a área em estudo. Isso inclui a
análise da competência das formações e a determinação das cargas admissíveis que o terreno pode
suportar. Este trabalho inclui pesquisa bibliográfica e exemplos práticos de estudos de prospeção
geotécnica.
O relatório inclui a análise de dois casos de estudo centrados na problemática das fundações, abordando
todas as fases do processo: desde a descrição do plano de prospeção geotécnica até o acompanhamento
dos ensaios in situ e a caracterização das litologias envolvidas. Os ensaios SPT (Standard Penetration
Test) e DPSH (Dynamic Probing Super Heavy) destacam-se como de particular relevância para os
resultados obtidos.
This report, titled "Comparison of in situ Test Results for the characterization of foundations in common buildings," was prepared as part of the Master's program in Geology, Applied and Environmental Geology, taught at the Faculty of Sciences of the University of Lisbon. The document is the result of a 9- month internship provided by the same institution in partnership with Betoteste, Gabinete de Estudos de Geotecnia, LDA. The main objective of this internship was to compile relevant information on the topic, with a focus on the most commonly used techniques in geotechnics, geotechnical prospecting, and foundation technology. During the internship, there was an opportunity to monitor various construction projects and interventions, discuss technical solutions, understand real on-site challenges, and gain professional experience in the field. The report is based on key concepts of geotechnical prospecting methods, essential for understanding the objectives of the in situ and laboratory tests performed. Additionally, it addresses the topic of foundations for common buildings. The role of the geologist, in this context, is to assess the ground conditions, obtaining geotechnical parameters through various tests, in order to provide detailed information about the study area. This includes analyzing the competence of formations and determining the allowable loads that the ground can support. This work includes bibliographic research complemented by practical examples of geotechnical prospecting studies. The report includes the analysis of two case studies focused on the issue of foundations, covering all phases of the process: from the description of the geotechnical prospecting plan to the monitoring of in situ tests and the characterization of the involved lithologies. The SPT (Standard Penetration Test) and DPSH (Dynamic Probing Super Heavy) tests are particularly noteworthy for the relevance of the results obtained.
