Applications of Optical Fiber Sensing Technology in Monitoring of Geotechnical Structures
Abstract The geotechnical structures will be inevitably suffered from material degradation and structural performance deterioration during the in-service operation stage. In order to acquire the on-line structural responses of each phase at the structural whole life-cycle (construction, operation, reinforcement, and rehabilitation), the structural health monitoring (SHM) systems based on the optical fiber sensing technology have been broadly implemented on a variety of geotechnical structures. The optical fiber sensors have received great concerns and been widely used in long-term geotechnical engineering monitoring due to their inherent advantages such as small size, light weight, immunity to electromagnetic interference (EMI) and corrosion, and embedding capability. Various monitoring purposes make optical fiber sensors get great advances in the manufacture and installation techniques as well as the analytical methods and theories. In this paper, the sensing principles of different types of optical fiber sensors are introduced. The applications of optical fiber sensing technology in different fields of geotechnical engineering are presented. The feasibility, reliability and effectiveness of optical fiber sensors in structural monitoring applications through laboratory tests and field experiments are described.
