摘要

Tunnel micro-deformation is a progressive mechanical response process of geotechnical media under the influence of stress redistribution, environmental loads, material aging and other factors. Its millimeter-level dynamic evolution is difficult to effectively capture by traditional monitoring technologies. Based on the physical mechanism of microwave remote sensing, this paper uses Ground-Based Synthetic Aperture Radar (GB-SAR) for continuous, non-contact deformation perception of tunnel structures. The system transmits and receives coherent electromagnetic wave signals, and extracts millimeter-level even sub-millimeter-level deformation information by means of differential interferometry technology. Combined with typical tunnel engineering cases, the study verifies the monitoring stability and reliability of the system under different geological conditions and complex environments. The results show that the system can realize real-time, high-precision monitoring of the full-section deformation field of tunnels with high early warning accuracy and strong environmental adaptability, providing an effective geophysical technical means for tunnel structure health diagnosis and safe operation and maintenance.
