Abstract: The application of the fiber grating sensing technology in monitoring the highway slopes has a rapid development in recent years. This paper presents the real time online monitoring results of a highway slope safety monitoring in Xiangshan County, Ningbo. A fiber Bragg grating sensing device is developed based on the mechanism of slope inclinometer. The local strength reduction method was used in the finite element analysis for the stability of the monitored slope and the displacement field was established. The real time online monitoring network system is also developed and the stability forecast can be implemented.
