摘要
隧道火灾和渗漏一直是隧道安全和健康的重要问题。基于分布式光纤测温系统(DTS)具有能实现在线实时监测且实测温度随光纤沿程分布这一技术特点和优势,将单根分布式光纤应用于隧道火灾的预警预报、火灾定位、隧道渗漏定位,属国内首创。本文介绍了DTS测温原理和实测成果。实测情况表明,DTS系统测温精确,抗干扰性强,特别适合隧道火灾预警预报和渗漏探测,具有良好的应用前景。
All along ,disastrous fire and leakage in tunnels are important problems about safety and health of tunnels. It is first time that single distributed optical fiber is applied in predicting disastrous fires and early-warning, as well as orienting fires and leakages, which is based on the technical characters and advantages that the Distributed Optical Fiber Temperature System（DTS） can realize monitoring in real time and on-the-spot surveying temperatures distribution along optical fibers＇ length. This paper introduces the principles of testing temperatures and testing results. The results show that DTS is accurate in testing temperatures and has good anti-jamming ability, especially fit to predicting and early-warning of disastrous fires and testing leakages, which has fair social benefits, economic values and good foregrouna.
