Application of BOTDA in Mass Concrete Temperature Monitoring
In order to study the application of distributed optical fiber in temperature monitoring of mass concrete, monitoring instruments are embedded in pile cap to carry out the field experiment. The results show that the distributed temperature fiber which is based on brillouin optical time-domain analysis (BOTDA) has the superiority of anti-jamming, corrosion resistance, high precision and continuous measurement. It can accurately reflect the temperature change, effectively guide the construction, and play a positive role in preventing the emergence of concrete cracks caused by temperature change. What’s more, optical fiber has small volume and less influence on engineering, which make it have a good application prospect.
