Research on Hidden Danger Investigation of Pipeline Geological Hazards Based on InSAR Technology
Surface deformation has always been a major threat to pipeline safety,and Tianjin is affected by various factors,resulting in uneven ground settlement.Using Sentinel-lA SAR image data of 108 periods from June 2017 to June 2020,and RADARSAT-2 SAR image data of 15 periods from December 2020 to November 2021,SBAS-InSAR technology were used to analyze surface subsidence in the Tianjin LNG pipeline route area.The results were compared and analyzed with the measurement results of land subsidence monitoring equipment,and the overall results were in good agreement,indicating the availability of InSAR technology in identifying geological hazards in pipelines,It can provide guarantees for the safe operation of pipelines.
