Recent Progress of Bridge Structural Health Monitoring Research in Chongqing University

摘要：

In this paper,a brief review of recent progress in the field of bridge structural health monitoring of the Opto-electronic Technology Lab of Chongqing University(OTLCU)was presented.The accuracy of the Extrinsic Fiber Febry-Perot(EFPI)sensor was studied,and its installation & protecting technique in civil engineering were introduced.Opto-electric deflection & displacement monitoring techniques,such as twodimension laser deflectometer,connected pipe opto-electric deflectometer and so on,were developed.As two implementation examples,a single-bridge health monitoring system and a three-bridge group health monitoring system were discussed,and some representative monitoring results were given.
