摘要:
为了预报松散含水岩层失水引起的沉降变形,采用预设钻孔埋入光纤Bragg光栅方法,对岩石变形进行监测,制作水泥砂浆试件4个,在实验室模拟预埋入光纤光栅砂浆试件的拉伸和压缩受力过程,测定光纤光栅波长偏移量,实验得出不同受力状态下光纤光栅的波长变化特征,采用光纤光栅传感技术是一种有效观测岩石变形的方法.
Abstract:
In order to forecast the subsidence deformation of the incompact hydrated strata because of the loss of water, adopting such ways that setting a drilling and burying fiber Bragg grating to inspect the rock deformation, making 4 concrete samples to simulate the process of pull and compression in the laboratory and measuring the excursion of wavelength, through experiment can get the different characteristic of wavelength changes under different pull and compression condition.The use of fiber Bragg grating sensor technique to detect the rock deformation is effective.
