摘要

为实现煤矿冲击地压的光纤光栅传感监测,从理论上分析了光纤光栅与冲击波的耦合机理。基于Housner随机激波模型,从理论上分析了激波与光纤光栅的耦合机理。结果表明,该波会改变光纤光栅的周期Ʌ和有效折射率n,进而影响初始波长值。冲击波的幅值、相位和频率与光纤光栅的波长漂移直接相关。冲击波在岩石中的传播速度受岩性特征的影响。岩石的弹性模量、密度和泊松比影响光纤光栅的初始波长值。该研究为利用光纤光栅监测煤岩爆提供了理论依据和实际应用指导。

Theoretical Study of Coupling Mechanism between FBG and Shock Waves of Rock Burst
To achieve the monitor of rock burst in coal mine with fiber Bragg grating (FBG) sensing, the coupling mechanism between FBG and shock waves was theoretically analyzed. Based on Housner’s random shock model, the coupling mechanism between shock waves and FBG was theoretically analyzed. The result shows that the wave will change the period Ʌ and effective refractive index n of FBG, and further affect the initial wavelength value. The amplitude, phase and frequency of shock wave are directly related to the wavelength drifts of FBG. The transmitting velocity of shock wave in rock is affected by lithologic characteristics. The Elastic modulus, density and Poisson’s ratio of rock influence the initial wavelength value of FBG. This study provided a theoretical basis and practical application guidance for coal or rock burst monitoring with FBG sensing.
