| Abstract: | Large numbers of cable-supported bridges will soon reach its 20-30 years lifetime of cables. It is urgently to carry out research on cables damage monitoring to assure bridge security. This paper introduces the fundamental of AE monitoring and the blind spots of parameter analysis. Then the advances in application of AE in bridge cable monitoring are described in detail including corrosion, fatigue and wire breakage. Finally combining with measured data analysis and the characteristics of local data, the problems that need to be solved for the AE method application in actual bridge are discussed and some research ideas also are introduced. |
