| Abstract: | In order to resolve the error of traditional FBG measurement, a new distributed inclination method that is based on new-type inclination tube and fiber Bragg grating (FBG) tilt sensor is proposed. The method uses improved inclination tube whose flexible deformation tube is connected to the PVC rigid tube. A new FBG tilt sensor with enhanced sensitivity structure is chosen as the high precision tilt sensor of the distributed inclination technology, and the fiber grating temperature sensor is used as the temperature compensation sensor. The application of the technology in the slope anti-sliding pile shows that this FBG inclination sensor-based technology is feasible and effective in engineering, and can successfully solve the problem of temperature compensation in the measurement. |
