光纤光栅仪器在长隧洞地质灾害监测中的应用

Application of Fiber BRAGG Grating Instrument in Geological Disaster Monitoring of Long Tunnel

进入21世纪以来,在社会经济稳步发展的背景下,我国隧道工程事业发展迅速。针对长隧道,在施工过程中为了确保施工的安全性,需做好安全监测方面的工作。光纤光栅仪器在长隧洞地质灾害监测中的价值作用显著,主要是光纤光栅仪器具备容量大,测量精度高,无零漂以及能适应各种恶劣监测环境等优势。在分析长隧洞地质灾害监测问题的基础上,进一步对光纤光栅仪器在长隧洞地质灾害监测中的具体应用进行探究,以期提高长隧洞地质灾害监测工作的质量。

Since the beginning of the 21st century, under the background of steady development of social economy, China's tunnel engineering industry has developed rapidly.For long tunnels, in order to ensure the safety of the construction during the construction process,it is necessary to do a good job in safety monitoring. The value of fiber Bragg grating instruments in the monitoring of long tunnel geological disasters is significant,mainly because of the advantages of large capacity, high measurement accuracy, zero drift and ability to adapt to various harsh monitoring environments. Based on the analysis of geological disaster monitoring problems in long tunnels,this paper further explores the specific application of FBG instruments in geological disaster monitoring of long tunnels, in order to improve the quality of geological disaster monitoring in long tunnels.
