초록

The special collapsible soil in the Loess Plateau region leads to a higher risk of settlement for the airport. Due to the limit of coverage, the method of obtaining data by manual measurement is gradually replaced by remote sensing monitoring. So, European Sentry 1A satellite is used to obtain the airport data, and the airport settlement is analyzed by using Small Baselines Subset Interferometry Synthetic Aperture Radar. The results show that there are three obvious settlement areas, including the parallel taxiway area on the west side of Xining Airport in the south, the parallel taxiway area on the east side and stands area near Terminal-2. The deformation areas show the characteristics of increasing settlement amount year by year and seasonal difference.
