Abstract

The harsh geological and climatic conditions in the high-altitude alpine regions of Northwest China, including the widespread distribution of seasonal permafrost and other unfavorable geological bodies, significantly affect the service life of highways and threaten driving safety. Traditional highway deformation monitoring methods are inefficient, limited in coverage, and provide incomplete deformation information. This study employs spaceborne InSAR technology for highway deformation monitoring, enabling large-scale extraction of deformation information along highway corridors. The findings reveal the deformation patterns of highway subgrades in permafrost regions, offering fundamental data for targeted remediation of hazardous highway sections. This approach ensures the scientific construction and safe operation of highways.
