Building risk monitoring and predicting based on method integrating mt-insar and pore water pressure model

Abstract

A method for InSAR assessment and prediction of risk level of urban buildings is provided, and includes the following steps: obtaining multi-channel SAR images of the urban buildings, extracting monitoring points in the multi-channel SAR images, and obtaining InSAR monitoring results of the urban buildings based on areas of the monitoring points, wherein the monitoring points comprise permanent scatterers and distributed scatterers; obtaining building outlines, obtaining deformation parameters based on the building outlines and the InSAR monitoring results, and assessing a building risk level based on the deformation parameters, wherein the deformation parameters comprise deformation velocity parameters and angle distortion parameters; constructing a stress-pore water pressure model, and carrying out a building risk prediction on the numerical simulation results based on set building risk level.
