摘要

For long-term monitoring of the deflection of Songjiazhuang cloverleaf junction on 309 national roads in Zibo, this paper proposed a CCD-based bridge deflection monitoring method. Based on DIC principle, the bridge deflection is measured by tracking of targets' position change in the FOV of CCD. The deflection monitoring software is compiled by MATLAB, and the deflection monitoring system for Songjiazhuang cloverleaf junction is integrated in this paper. This deflection monitoring system has functions such as 4-channel CCD cameras image preview, simultaneous acquisition, camera calibration, deflection display and data storage. Deflection curves obtained in the field show a consistent trend, this testifies that the proposed method is reliable and can meet the long-term monitoring requirements of bridge deflection.
