Deflection of the bridge, that is, the displacement of the bridge can be easily observed, and the safety diagnosis structure for measuring the deflection of the bridge structure to ensure the safety of the bridge by simply checking the displacement of the bridge due to the passage of the overload vehicle. It is about.

일반적으로 하천에는 사람이나 차량이 하천을 소통할 수 있게 하천을 가로질러 교량이 설치되어 있으며, 계곡과 같이 도로를 건설하기 어려운 지형에는 산과 산을 가로지르는 교량이 설치되어 있다. 특히, 우리나라와 같이 산악지형이 많은 곳에서는 지역과 지역간의 이동거리를 최소로 하기 위하여 교량의 건설 비중이 증가할 수밖에 없다.Generally, bridges are installed across rivers so that people and vehicles can communicate with them. Rivers and bridges across mountains are installed on terrains such as valleys where roads are difficult to build. In particular, in Korea where there are many mountainous terrains, the construction ratio of bridges is inevitably increased to minimize the distance traveled between regions.

이처럼 교량의 건설이 증가함에 따라 교량의 안전성 확보가 중요시되고 있다. 교량은 그 특성상 교각과 교각 사이에 교량 상판이 올려지게 되므로, 과적차량의 통행이나 교량 상판의 자체무게, 또는 계절의 변화에 따른 신축과 팽창으로 인한 상판의 처짐 현상이 발생되고 있다. 그리고 교량 상판의 처짐 현상은 교량의 안전성에 치명적이다. 그런데 이러한 교량 상판의 처짐 현상 즉, 교량의 상판이 처진 정도를 사람의 육안으로 확인하기에는 어렵기 때문에 이를 용이하게 확인할 수 있는 장비의 개발이 시급한 실정이다. As the construction of bridges increases, it is important to secure the safety of bridges. Since the bridge is raised between the bridge and the bridge nature of the bridge, the phenomenon of the top plate sagging due to the passage of overload vehicles, the weight of the bridge deck itself, or the expansion and expansion according to the change of the season is occurring. The deflection of the bridge deck is fatal to the safety of the bridge. However, it is urgent to develop equipment that can easily check the deflection phenomenon of the bridge deck, that is, it is difficult to check the degree of deflection of the bridge deck with the naked eye.
