Jinhai Bridge — 340m Box Girder Strain & Deflection Monitoring
Case Overview
Array grating deformation monitoring on the 340m main span box girder of Jinhai Bridge. UW-FBG arrays on bottom plate and left/right webs of the box girder achieved 4.34% strain/deflection inversion accuracy under static and dynamic loads. The system was integrated with the Guangzhou Railway monitoring platform.
Application Value
High-precision strain/deflection monitoring on a 340m cable-stayed bridge box girder with railway platform integration.
