Paper Abstract

This paper holds landslide monitoring system based on fiber optic sensors network. When structural distortion is occurred in landslide area, it will affect the change of fiber bragg grating space, and brings on the offset of the fiber bragg wavelength.The information of the destroyed point is obtained with the demodulated system.It applies annular distribution to mountain body, and establishs homologous fiber optic sensor network which collect all the information to the home site. This technique can provide the managers, policy-makers and experts the real time change of the parameters of the disaster, and the feedback can be given to monitoring station through the monitoring network. Therefore, it will be an important technical support for real time dynamic monitoring.
