Abstract

The identification of deformation hazards and the low efficiency of routine inspections in trunk highways present significant challenges. This paper addresses these challenges by utilizing MT-InSAR (Multi-Temporal Interferometric Synthetic Aperture Radar) technology to obtain surface deformation results from January 2021 to March 2023 in Jiaozuo City. Through the integration of highway road network vectors, a comprehensive evaluation of the occurrence of uneven settlement sections along the corridors is conducted. The findings reveal varying degrees of settlement experienced by Jiaozuo City during the specified period, with more significant surface subsidence observed in the northeast direction, attributed to the influence of mining areas. Notably, certain sections of the highways within a 1 km corridor exhibit a large annual average deformation rate and cumulative subsidence, indicating a severe impact of surface deformation disasters. This study provides valuable scientific support for the rapid and accurate assessment of surface deformation disasters in highway corridors using MT-InSAR technology, enabling a comprehensive understanding of their impact on highway infrastructure.
