摘要：
Aiming at the key problems of composite fiber optic devices for monitoring the slope slip according to an analysis of fuzzy mathematical theory of indoor physical model test, we studied the relationship between the slope displacement and the fiber loss response and the standard and calibration of the composite optical fiber devices. The results showed that the optimal grouting ratio of composite fiber devices at the substrates of PVC was 1:9, and the optimal slurry ratio of the composite fiber device of expanded polystyrene (EPS) substrate was 1:5. In addition, the relationship between the slope slip displacement and fiber loss response in the optimal grouting ratio was obtained. At the same time, to ensure the effectiveness and uniformity of composite optical fiber devices in landslide monitoring, we proposed the implementation standard and calibration method of the device. The cost of the composite optical fiber device to monitor the slope is lower than that of the fiber optical fiber sensor in the laser.
