Abstract

Practical capabilities of Ground Penetrating Radar (GPR) method in engineering diagnostics of defects arising and developing in time under operating loads in bulky reinforced concrete constructions are considered. GPR method makes it possible to detect and locate defects in concrete and metal structural components. As an illustration of vast GPR method capabilities, the results of many years’ investigation of underwater Kanonersky road tunnel in St-Petersburg are adduced. Beginning from 1998, GPR method was successfully used for qualitative estimation of the state of pavement at the tunnel foundation both before and after repair work, the latter was the cementation. Merits of GPR method and its development prospects are described.
