High-precision slope deformation monitoring of transmission towers using insar technology: implications for infrastructure stability and risk management

Abstract

With the increasing complexity of power transmission systems and the exposure of power line pylons to environmental stressors, the study of slope deformation becomes pivotal to ensure structural stability and operational reliability. This research presents an in-depth analysis of slope deformations associated with power line pylons using Interferometric Synthetic Aperture Radar (InSAR) technology. The significance of InSAR in the geotechnical monitoring field is established through a comprehensive theoretical framework, detailing its capacity for high-precision deformation measurements over extensive areas. A series of case studies demonstrate the efficacy of InSAR in detecting and monitoring slope instabilities surrounding power line pylons. Adopting a sophisticated methodology for InSAR data processing, the study further investigates slope stability, integrating various analytical techniques to discern deformation patterns and potential failure modes. The results underscore the critical role of InSAR in predicting and mitigating risks associated with slope-induced pylon deformations. The paper concludes that InSAR is an indispensable tool for maintaining the structural integrity of power transmission infrastructure, yielding substantial implications for both geotechnical engineering practices and the development of preventive maintenance strategies. This contribution to the field not only promotes the advancement of remote sensing applications in engineering geology but also underscores the necessity for technology-driven solutions in safeguarding vital utility infrastructure.
