ZHANG Feng-mei, LEI Zhen-shan, LIU De-he. Application of fiber Bragg grating sensing technique in bridge construction monitoring[J]. 2006, (2): 78-80. DOI: 10.13873/j.1000-97872006.02.027.
In order to fulfil the complex requirement of monitoring bridge construction with incremental launching method
the structure and principle of fiber grating sensor is analyzed.Some key issue about the application of fiber Bragg grating(FBG) is also studied
for example the temperature and strain cross sensitivity
wavelength demodulation.The parameter of FBG sensors is designed by analyzing the force on bridge piers and the deformation of bridge piers.Combined virtual instrument with FBG sensor can make use of the advantages of virtual instrument in data acquisition
signal analysis
data storage and communication to realize FBG demodulation and construction monitoring in one system
the safety of construction and quality of bridge is guaranteed.
