A STUDY OF MEASUREMENT AND ADMINISTRATIVE MAINTENANCE INFORMATION SYSTEM OF CIVIL ENGINEERING STRUCTURES USING OPTICAL FIBER TECHNOLOGY

In recent years, the Information Technology (IT) has been utilized in various fields of civil engineering. Especially, trials have been made to utilize optical fibers as sensors to measure strain of civil engineering structures, ground deformation, temperature, etc., and they have been installed for measuring in the civil engineering structures including tunnel, river embankment, and cut-slope soil structures. In order to make such optical monitoring systems of civil engineering structures more general and organic systems, it would be effective to combine them with such comprehensive telecommunication systems. The infrastructure structure measurement and maintenance system is accumulation and collection system and processing/offering/exchanging system, and the network where information is additionally transmitted is needed. We investigate the construction of general monitoring systems of civil engineering structures which can perform thorough management from monitoring to maintenance utilizing telecommunication networks technology.
