Progress of Fiber Grating Sensor Development and Its Application in Bridge Engineering
In this paper,the structural types,implementation methods and key technologies of surface-applied,fiber-reinforced polymer,tube-type and embedded encapsulated fiber Bragg grating sensors(FBGS)from the perspective of sensor types are introduced,then the working principles,technology development and engineering application progress of various encapsulated sensors are briefly described,and the advantages and shortcomings of sensors in different encapsulation methods are summarized.Next,the typical engineering application cases of FBGS in bridge structure condition monitoring/inspection are briefly presented.Lastly,the process engineering method,durability and distributed measurement of FBGS in civil engineering and the key problems to be solved for its future promotion and application are pointed out,providing references for the optimization of FBGS technology and its promotion and application in civil engineering.
