| Abstract(in English) | In prestressed concrete bridge, a gap which has formed inside the prestressed concrete (PC) bridge by non-filling grout to a sheath sometimes influence on safety of PC bridge. In this report, we did the measurement experiment for applying the proposed non-destructive inspection method using a PC bridge sample structure. Moreover, we analyzed shock wave propagation in a PC bridge sample structure by using Finite-Difference Time-Domain (FDTD) method. And we evaluated the effectiveness of the proposed non-destructive inspection method. |
