Abstract
본 발명은 일반적인 교량 구조물에 전자파 또는 전자기장에 상당히 안정하고 직경이 수십 마이크론 정도로 소형인 광섬유 센서를 메설하여 교량에 대한 하중 변화, 진동 변화 및 스트레인 레벨 변화를 측정함으로써 스트레인에 의한 교량의 붕괴를 장기적으로 미연에 방지할 수 있는 광섬유 스트레인 센서를 이용한 교량 안전점검 방법에 관한 것이다.The present invention is to install a fiber optic sensor that is fairly stable to electromagnetic waves or electromagnetic fields in a general bridge structure and small in diameter of several tens of microns and to measure the load change, vibration change and strain level change for the bridge to prevent the collapse of the bridge due to strain in the long term. The present invention relates to a bridge safety inspection method using an optical fiber strain sensor that can be prevented in advance.
본 발명의 방법은 광섬유 센서를 이용해서 보다 정확이 장기간 동안 교량 붕괴의 원인이 스트레인 발생을 미연에 방지할 수 있게된다.The method of the present invention makes it possible to prevent the occurrence of strain, which causes the bridge collapse for a longer period of time more accurately using the optical fiber sensor.
