【摘要】：隧道二次襯砌性能劣化是影響隧道健康運營的主要病害,對隧道二次襯砌進行監(jiān)測是保證隧道健康運營的重要手段。應(yīng)用埋入式光纖Bragg光柵應(yīng)變傳感器深入研究了隧道二次襯砌的變化。通過FBG(Fiber Bragg Grating)傳感器在隧道內(nèi)的布設(shè)及溫度補償技術(shù),對隧道斷面的應(yīng)變變化情況進行了分析。結(jié)果表明,數(shù)據(jù)的曲線走勢在一定程度上反映了隧道二次襯砌的變化,為進一步的病害預(yù)報提供了有效的支持。
[Abstract]:The deterioration of the two lining performance of the tunnel is the main disease affecting the healthy operation of the tunnel. Monitoring the two lining of the tunnel is an important means to ensure the healthy operation of the tunnel. The embedded fiber Bragg grating strain sensor is used to study the changes of the two lining of the tunnel. The installation of the FBG (Fiber Bragg Grating) sensor in the tunnel is used. And the temperature compensation technology is used to analyze the strain change of tunnel section. The results show that the curve trend of the data reflects the changes of the two lining of the tunnel to a certain extent, and provides effective support for the further disease prediction.
