Abstract

Abstract:

Ground fissure is a kind of unique urban geological disaster,which is more and more widely distributed in China,but humans can't stop it.This seriously hinder the development of economic construction and people's life and property.In this paper,we use differential interferometry synthetic aperture radar(DInSAR),taking Langfang city as study area,based on 3 screens RADARSAT-2 data from June 2016 to November 2016 to obtain the information of surface deformation in the area by means of DInSAR,and reference to the ground fissure information in 2009.Besides the distribution and trend of ground fissures will be analyzed and predicted for the production units and local government departments to decision basis on the treatment and prevention of the ground fissures.

Key words: ground fissure, disaster, differential interferometry synthetic aperture radar (DInSAR), surface deformation
