“…A escolha e utilização de um método depende da finalidade e características do projeto. Assim, a deteção de fraturas pode utilizar GPR [19] e tomografia de ultrassons [20], enquanto a investigação de patologias, como humidade em paredes, pode recorrer a tomografia elétrica [21][22] que também pode ser usada para a caracterização de terrenos e fundações sob edifícios [23][24].…”

ResumoA caracterização do Mosteiro da Batalha incluiu o método de prospeção geofísica de radar de penetração no solo (GPR). Este método, não destrutivo e indireto, permite obter imagens 2D/3D de elevada resolução das estruturas investigadas. Devido à natureza do estudo, foram utilizadas grelhas de medida e parâmetros de aquisição adequados, elevada precisão da localização dos pontos de leitura e processamento de dados adaptado. O GPR clarificou questões relacionadas com a construção e o estado de conservação do Mosteiro. São apresentados resultados da investigação do terreno sob o Mosteiro, localizando infraestruturas recentes e antigas, fundações de colunas e estruturas de interesse histórico-arqueológico. A caracterização de elementos construtivos justificou a utilização do GPR na superfície das paredes do claustro de D. João I, permitindo propor uma estrutura interna do aparelho construtivo das paredes. O GPR provou ser eficaz e expedito e permitiu obter informação indispensável para contribuir para a preservação, recuperação e reabilitação do monumento. AbstractThe characterization of the Monastery of Batalha included the use of the geophysical method of ground-penetrating radar (GPR), a non-destructive and indirect method that provides highresolution 2D/3D images of the structures to investigate. Owing to the nature and aims of the survey, appropriate measurement grids, acquisition parameters and adapted data processing techniques were used. The GPR survey provided important information about the Monastery foundations, construction and conservation. GPR high-resolution images allowed to locate recent and ancient infrastructures, columns foundations and structures of historical-archaeological interest. The characterization of the Monastery walls was also carried out using GPR on the surface of walls of the Cloister of D. João I and of the Church. These results contribute for the proposal of an inner structure model of the walls. GPR proved to be an efficient and expeditious method that allowed obtaining information to be used in the preservation, recovery and rehabilitation of the Monument.

This study presents a procedure in which 3D electrical resistivity tomography (ERT) and ground-penetrating radar (GPR) were used to determine singularities in the foundations of protected historic towers, where space is limited due to their characteristics and location in highly populated areas. This study was carried out on the Tower of the Cathedral “Santa Iglesia Catedral de Santa María” in Murcia, Spain. The novel distribution of a continuous nonlinear profile along the outer and inner perimeters of the Tower allowed us to obtain a 3D ERT model of the subsoil, even under its load-bearing walls. This nonlinear configuration of the electrodes allowed us to reach adequate investigation depths in buildings with limited interior and exterior space for data collection without disturbing the historic structure. The ERT results were compared with GPR measurements and with information from archaeological excavations conducted in 1999 and 2009. The geometry and distribution of the cavities in the entire foundation slab of the Tower were determined, verifying the proposed procedure. This methodology allows the acquisition of a detailed understanding of the singularities of the foundations of protected historic towers in urban areas with limited space, reducing time and costs and avoiding the use of destructive techniques, with the aim of implementing a more efficient and effective strategy for the protection of other tower foundations.
