SOUNDNESS MONITORING SYSTEM AND SOUNDNESS MONITORING METHOD
PROBLEM TO BE SOLVED: To provide a soundness monitoring system that reduces the burden of continuously monitoring the soundness of bridges and improves the accuracy of soundness assessment.SOLUTION: The soundness monitoring system includes monitoring devices 4A to 4C installed on each pier of a bridge and a soundness evaluation device. Each of the monitoring devices 4A to 4C includes an acceleration sensor 45 for measuring fine movement at all times of each pier, an analysis unit 46 for calculating a power spectrum area ratio of each bridge on the basis of measurement data, a storage unit 47, a communication unit 48, and a power supply unit 49 that supplies power to each of the acceleration sensor 45 and the analysis unit 46. The soundness evaluation device calculates a difference in power spectrum area ratio between any two of the monitoring devices 4A to 4C.SELECTED DRAWING: Figure 2
【課題】橋梁の健全度を継続的に監視するための負担を低減し、かつ、健全度評価の精度を向上させる健全度モニタリングシステムを提供する。【解決手段】健全度モニタリングシステムは、橋梁の各橋脚に設置されるモニタリング装置４Ａ〜４Ｃと、健全度評価装置とを備える。モニタリング装置４Ａ〜４Ｃは、各橋脚の常時微動を測定する加速度センサ４５と、測定データに基づいて各橋脚のパワースペクトル面積比を算出する解析部４６と、記憶部４７と、通信部４８と、加速度センサ４５及び解析部４６の各々に対して電力を供給する電力供給部４９と、を備える。健全度評価装置は、いずれか２つのモニタリング装置４Ａ〜４Ｃ間のパワースペクトル面積比の差分を算出する。【選択図】図２
