| Abstract: | Fiber grating sensing and monitoring technology has such advantages as strong anti interfere performance,good long term stability,absolute value measuring and distributing sensing,etc.Based on the experimental study which fiber grating sensing technology was applied in civil engineering structure for reinforcing monitoring,the FBG sensors were laid in three typical bridge structures in Wuhuang highway which had been built before,to collect data which were used to evaluate the effect of reinforce projects. |
