Abstract
The deflection of a bridge structure is a comprehensive reflection of the operating state of the beam body, and is an important indicator of the bearing capacity of the structure. Especially after heavy loading and speed increase, in order to ensure driving safety, the engineering management department must grasp the change law of the deflection of the beam body in time. There is an urgent need for a measuring instrument that is simple to operate, fast to install, highly practical, and convenient for measuring beam deflection. Based on the comparison of the four commonly used methods for beam deflection measurement in China, a scheme for deflection measurement based on CCD imaging processing technology based on computer BIM technology is proposed, and a bridge deflection measuring instrument is developed for field use. The comparative experiment of on-site bridge deflection measurement proves that the error between the measurement results of the instrument and the measurement results of the bridge deflection special instrument is only 3.0% to 6.9%, which meets the engineering requirements.
