Paper Abstract

Landslide is typical geo-hazards which causes serious threat to the human lives and infrastructures. It's necessary to develop a monitoring system to avoid landslide disasters. In this paper, a real time monitoring system based on optical fiber sensing technology was designed to monitor the health status of slope. Three types of optical fiber sensors, including FBG strain gauge embedded in anchor, FBG inclinometer, and FBG soil-pressure sensor, were demonstrated. A light switch was introduced to expand the demodulation equipment to 16 channels, which enlarges the capacity of more than 200 FBG sensors. This remote and real-time monitoring system can be used not only for landslide monitoring but also for large scale structure health monitoring.
