Deformation of the Great Wall intersected with roads based on PS-InSAR
With the continuous expansion of transportation networks,modern roads have intersected the ancient Great Wall,which triggers deformation effects on the wall and becomes a concerned issue. To gain a deeper understanding of the impact of roads intersecting the Great Wall on its deformation,this study employed persistent scatterer-interferometric synthetic aperture radar (PS-InSAR) technology to conduct a detailed deformation analysis of the areas surrounding the Great Wall. The research reveals that the act of roads intersecting the Great Wall significantly affects its deformation patterns,particularly evident in specific regions with notable ground subsidence. This deformation is manifested as stretching and compression of the Great Wall within the regions of road intersection,leading to a maximum cumulative subsidence of 75.2 m. In these affected regions,the subsidence rate of the Great Wall even reaches 24.6 m per year. Through comprehensive analysis and presentation of the vibration-induced deformation information of the Great Wall,the study unveils the pronounced deformation effects caused by roads intersecting the Great Wall. This research outcome not only holds practical value for the conservation and management of the Great Wall but also provides robust reference and inspiration for deformation studies in similar regions.
