Abstract

Weak fiber grating sensing technology has started to be applied in various fields, and its introduction into landslide monitoring can realize comprehensive monitoring of points, lines and surfaces. In this paper, on the basis of introducing the principle of weak fiber grating, weak grating displacement sensor, inclination sensor, weak grating optical cable and weak grating demodulator are combined to build a weak grating sensing real-time monitoring system, and finally a weak grating real-time monitoring application test of a landslide is given. The test results show that the weak fiber grating sensing real-time monitoring system can achieve real-time monitoring of landslides, and its experience can be extended to other landslides of weak fiber monitoring.
