The bridge heavy vehicle identification system based on optical fiber sensing technology

Abstract

In order to meet the research of bridge health and safety monitoring system, and provide heavy vehicle load spectrum for the research, the heavy vehicle classification identification system was designed based on high-speed FBG demodulation system and FBG sensing test technology according to the structure characteristics of the large span orthotropic steel box girder cable-stayed bridge. The heavy truck load cases were designed for the loading test, and heavy vehicle classification standard was provided of the identification system according to the loading test.Keywords: optical fiber sensing technology, high-speed demodulation, heavy vehicle identification, bridge health and safety monitoring system, orthotropic steel box girder
