Analysis of Bridge Health Monitoring System for Hongfenghu Bridge based on Limited Sensors

摘要

Guiyang Hongfenghu bridge health monitoring system was designed in this paper. The strain of girder was monitored by FBG sensors and cable force was monitored by piezoelectric accelerometer, meanwhile vertical motion of girder was monitored by vibration accelerometer and inclinator was applied to tower offset monitoring. Then, the information of multi-heterogeneity sensors was integrated to remote monitor by optical fiber transmission.
