A STUDY ON THE BEST SPECIFICATION OF THE INSPECTION DEVICE OF TUNNEL CONCRETE LINING

Abstract

We are developing a new inspection technique for tunnel concrete lining using shock acoustics, which mechanizes and automates a work from shock to the health judgment.
Furthermore we have researched the method of making the shock energy constant and recording shock acoustics without changing the frequency characteristic. As the result, we were able to decide the better specification of the inspection device.
