【摘要】：隧道二次衬砌性能劣化是影响隧道健康运营的主要病害,对隧道二次衬砌进行监测是保证隧道健康运营的重要手段。应用埋入式光纤Bragg光栅应变传感器深入研究了隧道二次衬砌的变化。通过FBG(Fiber Bragg Grating)传感器在隧道内的布设及温度补偿技术,对隧道断面的应变变化情况进行了分析。结果表明,数据的曲线走势在一定程度上反映了隧道二次衬砌的变化,为进一步的病害预报提供了有效的支持。
[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.
