Paper Abstract

The information and the necessity of engineering monitoring of Dongying Yellow River Bridge are briefly introduced firstly. And then the application of optical fiber sensors in construction supervision, loading test and health monitoring of this bridge is illuminated. The distribution of the internal force monitoring sections, strain and temperature monitoring points and the measuring contents are concisely analyzed. The Encapsulation techniques, installation means and protective measures of optical fiber sensors used in this bridge are also clarified. The author emphasizes the comparison between the theoretical results and actual measuring data derived from optical fiber sensors under some load cases of all the three monitoring phases, which shows that the measuring data is accurate and reliable. Considering its other merits, the author proves that the optical fiber sensors fit the monitoring of large bridge. At last, the outline of health monitoring system integration, especially the accessing of sensors to Interrogator, is showed and the mode of date acquisition, display and analysis, through the long range wireless transmission, is specified.
