| Abstract | Civil infrastructures are affected by climate change including sea level rise, changes in snowfall, ice, and permafrost, and effects on hydrological systems, including precipitation floods and droughts, tropical cyclones, storms, and sea-wave heights. Also, disasters such as earthquakes, landslides, and tsunamis worldwide disrupt people’s lives and cause significant property damage. This study investigates the recent advancements toward damage mitigation of civil infrastructures through early detection of natural disasters and climatic changes using the measurements of optical fibre sensing (OFS) followed by deep learning (DL) models. It was shown that pointed and distributed OFS was effective for measuring strain, temperature, and pressure to trace the changes in seismological, hydrological, and geological data at surface level, subsurface level, and submerged. OFS is a rapidly growing research area for improving inspection accuracy and performance due to its advantageous properties of being lightweight, reliable, small in size, immunity to external electromagnetic perturbations, low power, high sensitivity, multiplexing capability, and wide bandwidth. Distributed optical fibre sensing (DOFS) has gained immense interest in engineering as they offer unique advantages for spatially distributed measurements for hundreds of kilometres. DOFS could detect the damage's precise location, magnitude, and propagation over time. Climate changes and disasters triggered propagating damage to structures including buildings, bridges, highways, and dams can be identified in terms of cracks, fatigue, creep, and slip. Big data-driven methods for disaster management are developed with DL, most frequently through convolutional neural networks. DL-based disaster-predicting systems that can be identified with seismological data have been developed with precision and a recall of over 90%. This review reveals that disasters due to earth movements and pore water pressure can be precisely detected through OFS followed by DL models. There is ample room for further development of combinational studies between OFS and DL for disaster and climate change risk assessment. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. |
