项目摘要

For the aim at establishment of long term monitoring system for bridge maintenance by the high accurate structural identification, we develop the theory, monitoring system, and conducted field tests for the realization. The results were described as follows.1)Development of the automatic structure identification engine for the high precision structure identification robotTo accomplish structural identification, we developed two structural identification methods, which are 1)The two-step estimation method based on AR model, and 2)The ERA method.2)Verification of the precision of the automatic structure identification engineBy using the two automatic estimation engines, the vibration character of the bridge could be estimated in the high precision as a result of doing the verification for 5D.O.F. model and Langer Bridge.3)Development of the automatic vibration characteristic estimation system for the high precision structure identification robotA super-high precision structure identifica … More tion robot system is consisting of sensing part, data transmission part, and data accumulated part. It was applied to the actual bridge structure thing, and that utility was confirmed.4)Actual bridge long-term monitoring by the super-high precision structure identification robotThe super-high precision structure identification robot was applied to long term monitoring of the Kadoma Bridge in Osaka, and the Kabashima Bridge in Nagasaki. We found that the yearly change of temperature affect the vibration characteristics of those bridge. It means that we should care about the influences by the environments for monitoring the structure's frequencies. It is working even at present, and this measurement is continuing data accumulation.5)Development of the bridge construction management, and measurement control system by the wireless LANBy using above mentioned system, a bridge construction management and measurement control system were developed. The rationalization of the computerized execution and the construction could be realized by the remote monitoring of the cable vibration measurement data.6)Development of the light weight multiple functions measurement module and application to that bridge monitoring systemA bridge static change analysis by the live load, and a bridge dynamic change analysis were realized with the light weight multiple functions measurement module. Also, the practical experiment of the measurement of the traffic flow by the Internet camera was done, and that validity was confirmed. Less
