GPR and sonic tomography for structural restoration : the case of the Cathedral of Tricarico

Abstract

In this paper, we present the results of a diagnostics survey, based on the exploitation ofground penetrating radar (GPR) and sonic prospecting, to characterize the deterioration statusof the pillars of the cathedral of Tricarico, in the Basilicata region (Southern Italy). Theprospecting falls within the more general framework of investigating the structural conditionsof this monument, which is affected by heavy instability problems. This study case points outthe great effectiveness of the two employed diagnostic methods, when used in an integratedway, for detecting cracks and inhomogeneities in the inner structure of masonry buildingelements. With regard to GPR prospecting, a comparison is made between the results obtainedby a standard processing and those obtained by means of an inverse scattering algorithm. Forone of the investigated pillars, the results obtained from non-invasive tests are compared withthose of direct inspection. This is performed by coring the pillar and examining both the coreand the hole (the latter by means of an endoscope). The seismic investigation allowed us toprove the mediocre or bad state of conservation of the pillars.
