Abstract

Distributed fiber optic sensing technology is based on Raman scattering and optical time-domain reflection technologies, and consists of two parts: the demodulation host and the fiber optic cable. The system obtains the structural changes of the building through the sensing fiber optic cable, such as sensing the strain, crack, tilt, settlement and other specific changes of the dam and other buildings. By calculating the structural safety condition of the building, the system determines the structural safety level of the dam and other buildings according to the judgment standard of structural safety of the dam and other buildings and the subsequent treatment and remedial measures. Realize the long-term online monitoring of the structural safety of dams and other buildings, and provide long-term sustainable structural safety guarantee for dams and other buildings.
