Abstract
As a result of its own and external factors, the concrete structure is easy to produce cracks. The cracks seriously affect the safety of the structure. Therefore, in order to ensure the durability of the structure, it is necessary to monitor the cracks of the concrete structure. Due to the time and position randomness of concrete crack formation, the fully distributed sensor is an ideal way to capture concrete cracks. However, when the fully distributed sensor is used for large-scale measurement, the drift of spatial position of the optical fiber along with the external temperature, strain, and other external environmental changes will occur. Therefore, aiming at the positioning of concrete crack, this chapter focuses on solving the problem of fiber accurate positioning in engineering application. From the basic principle of Brillouin sensing and fiber grating, the locating drift problem of fully distribution optical fiber is discussed, and the concrete crack monitoring technology based on fully distributed optical fiber sensing is established.
