光纤光栅传感器在路基沉降监测中的应用研究，
An application of fiber Bragg grating in the monitoring of railway roadbed deformation
摘要
Abstract
We develop a temperature-unaware fiber Bragg grating （FBG） displacement sensor in view of big labor-consumption in the monitoring of railway roadbed deformation and no acquisition of real-time road information. It has the measurement range of 100 mm and measurement accuracy of 0. 1 mm. Data analysis of more than two months scene test shows that the designed sensor can reflect the real-time information of the railway roadbed deformation, especially for the information of the negative influence of precipitation on the rate of roadbed deformation.关键词
