[0002] As a crucial component of transportation infrastructure, tunnels' safety and stability directly impact the smooth flow of traffic and the safety of passengers. However, during long-term use, tunnels are prone to various defects due to factors such as geological conditions, climate, construction quality, and operational load, including water leakage, lining cracks, frost damage, and corrosion. These defects not only affect the tunnel's service life but can also lead to serious safety accidents. Therefore, regular tunnel defect detection and maintenance are essential.
