AdvancesIn Application of Optical Fiber Sensing Monitoring Technology in Engineering Geology

In recent years, with the development of more and more engineering construction and the emergence of urban geological disasters, long-term effective structural stability monitoring in engineering geology is very important. As a new monitoring technology, optical fiber sensing has the advantages of high precision, remote real-time, long distance, long durability and anti-electromagnetic interference. It can make up for the shortcomings in traditional monitoring technology engineering monitoring and is widely used. This paper summarizes the application status of fiber optic sensing monitoring technology in tunnel structure health monitoring, ground deformation monitoring, foundation pit monitoring and slope monitoring by summarizing the related research work of the predecessors, and draws some conclusions and reflections:(1) Optical fiber sensing monitoring technology conforms to the development strategy of engineering geology; (2) Optical fiber monitoring should be organically and deeply integrated with multidisciplinary; (3) Distributed (quasi-distributed) fiber monitoring technology has broad application prospects in engineering geological monitoring.
