The mountain landslide has been the disaster which makes the one great harm in the nature. People have been looking for better monitoring of how the preceding information to the landslide. And developed a number of commonly used monitoring methods, but they have advantages and disadvantages. Recently, optical fiber sensing technology is coming into people's vision gradually. For monitoring optical fiber has many advantages to traditional methods. In this paper, based on a lot of reading literature, a new optical fiber monitoring method and composite optical fiber testing device is proposed. The device based on optical time domain reflectometry (Optic Time Domain Reflectomery) to achieve high initial accuracy, large range and direction of the judge.This article mostly finished work has hereinafter several aspect:①Analyzed optical fiber sensor used in mountain landslide both here and abroad research actuality.②From the butterfly bow of the study we designed the fiber composite and complex optical fiber devices which used in testing research, internally or externally, and achieved good results.③Explored the way based on the light reflected in the field of technology, remote and immediate synchronize access to information, confirm the basic method of soil and rock physical movements to reveal the landslides arising from the law of motion and mechanics.④Take efforts to establish a mechanism to monitor the optical fiber device based on the slope stability of the experiments carefully and with the apparatus, as compared to a landslide for geological,to provide effective disaster prediction.
