An embodiment provides a deflecetion control system of a bridge upper structure, which comprises: a hydraulic jack positioned below the bridge upper structure to raise the bridge upper structure; and an electric control device connected to the hydraulic jack, configured to detect horizontal movement of the bridge upper structure from a plurality of sensor units installed at an end of the bridge upper structure, and configured to control operation of the hydraulic jack according to information of the sensor units. According to the present invention, the deflecetion control system of a bridge upper structure detects deflection occurrence in a longitudinal direction on a flat surface vertical to a raised direction of the bridge upper structure, which may occur when raising the bridge upper structure. Therfore, the bridge upper structure can be safely raised by performing raising control.

    실시예는 교량 상부구조물을 인상하도록 상기 교량 상부구조물 하부에 위치하는 유압잭; 그리고 상기 유압잭과 연결되며, 상기 교량 상부구조물의 단부에 설치되는 복수의 센서부로부터 상기 교량 상부구조물의 수평 이동을 감지하고, 상기 센서부의 정보에 따라 상기 유압잭의 동작을 제어하는 전기제어장치를 포함하는 교량 상부구조물 변위 제어 시스템을 제공한다. 따라서, 본 발명에 따른 교량 상부구조물 변위제어시스템은 교량 상부구조물 인상 중 발생할 수 있는 교량 상부구조물의 인상 방향에 수직한 평면에서의 종횡방향으로의 변위 발생을 감지하고, 이에 따라 인상 제어를 수행함으로써 안전하게 교량 상부구조물을 인상할 수 있다.
