Abstract

Transmission lines in Sichuan area play an important role in electric power system. Due to frequent geological disasters mainly based on landslide in Sichuan area, transmission towers will suffer from tilted, uneven subsidence and horizontal sliding due to ground deformation, which directly endangers the safety of power towers and stable operation of line. Therefore, it is of great significance to study the influence of surface deformation on transmission tower construction and operation under complex surface conditions. In view of the complex terrain conditions in Meigu County, Liangshan Yi Autonomous Prefecture, Sichuan Province, this paper adopts the time-series InSAR deformation monitoring technology, and calculates the SBAS-InSAR deformation rate and deformation time series on the basis of data preprocessing and differential interference processing, and obtains the geocoding deformation monitoring results. According to the deformation rate of the monitoring area, the deformation time series of the sampling point and the landslide hazard
