Određivanje mogućnosti georadara u ocjeni stanja konstrukcija

The condition assessment of structures using the non-destructive ground penetrating radar (GPR) method is based on the analysis of the strength, sign and shape of the signal reflected from the objects under the examined surface. Therefore, it is used for locating reinforcement in reinforced concrete structures, determining the type and structure of structural elements, evaluating the corrosion of reinforcement, etc. This paper presents the applicability of the GPR method for locating reinforcement and determining the geometry of structural elements, as well as the study of the sensitivity of the GPR signal to chloride-induced corrosion parameters.Ocjena stanja konstrukcija nerazornom metodom georadar (GPR) temelji se na analizi jakosti, predznaka i oblika reflektiranog signala od objekte ispod ispitivane površine. Stoga se koristi za lociranje armature u armiranobetonskim konstrukcijama, određivanje vrste i strukture konstruktivnih elemenata, ocjenu korozije armature, itd. U ovom radu prikazana je primjenjivost georadara za lociranje armature i određivanje geometrije konstruktivnih elemenata, kao i studija o osjetljivosti signala georadara na parametre korozije izazvane kloridima
