Road line selection geological stability evaluation method based on InSAR (Interferometric Synthetic Aperture Radar) technology

The invention discloses a road line selection geological stability evaluation method based on an InSAR technology, and belongs to the technical field of road engineering. The method comprises the following steps: acquiring a wide-area InSAR overall deformation rate condition of a road line selection area; outliers in the deformation data are removed, and a total quantile is calculated; according to the total quantile, an active fault zone grid is identified, and an active fault zone influence area range is calculated; according to the total quantile, a settlement grid is identified, and a settlement influence area range is calculated; and according to the identification result of the active fault zone and/or the settlement influence area range, suggestions for avoiding or further investigation and analysis are given. The invention creatively provides the active fault zone and settlement zone identification method based on InSAR data, the area influencing road construction is identified according to the surfac
