Application of fiber Bragg grating inclinometer to deformation monitoring of geotechnical slope
摘要
Abstract
Considering the deficiency of inclinometer and the advantage of the fiber Bragg grating sensing technology,the fiber Bragg grating inclinometer that can monitor the internal deformation of geotechnical slope was developed in the paper. Meanwhile a new type inclinometer was used successfully on the de-formation monitoring of expansive soil slope of highway. In-site monitoring data show that the monitoring data of fiber Bragg grating inclinometer coincide with those of the conventional inclinometer,and the relia-bility of fiber Bragg grating inclinometer was proved. Meanwhile it is found that the maximum deformation of slope appears on the second section of slope and the deformation is 61 mm,and the deformation of the first section of slope is much smaller,namely,about 13 mm. And it is proved that setting slope retaining wall in the slope foot can dramatically improve the stability of slope. A monitoring network system can be formed with the fiber Bragg grating inclinometer and other fiber Bragg grating sensor which can also be used in deformation monitoring of geotechnical slope. With the network signal transmission,the long-tern real-time online monitoring,early safety warning on internal deformation of geotechnical slope can be a-chieved.关键词
