【摘要】：通過(guò)分析雙列雙邊授流情況下雜散電流的分布和雜散電流對(duì)金屬管道的腐蝕模型,得出雜散電流對(duì)金屬管道的腐蝕模型。在分析拱頂混凝土開(kāi)裂過(guò)程的基礎(chǔ)上,研究了雜散電流對(duì)隧道拱頂沉降的影響。為了實(shí)現(xiàn)對(duì)隧道拱頂沉降的實(shí)時(shí)監(jiān)測(cè),提出了一種新的基于光纖光柵傳感器的監(jiān)測(cè)方法。采用匹配光柵解調(diào),實(shí)現(xiàn)了拱頂沉降的辨識(shí),進(jìn)而建立了拱頂沉降模型,最后通過(guò)仿真檢測(cè)沉降模型的正確性。
[Abstract]:Based on the analysis of the distribution of stray current and the corrosion model of metal pipeline caused by stray current, the corrosion model of metal pipeline is obtained. On the basis of analyzing the cracking process of concrete in arch roof, the corrosion model of metal pipeline is obtained by analyzing the distribution of stray current and the corrosion model of stray current on metal pipe. The effect of stray current on tunnel dome settlement is studied. In order to realize real-time monitoring of tunnel dome settlement, a new monitoring method based on fiber Bragg grating sensor is proposed. Furthermore, the model of dome settlement is established, and the correctness of the model is tested by simulation.
