摘要
地裂缝是一种独特的城市地质灾害,在我国分布越来越广,但人类无法阻止其活动,这严重阻碍我国经济建设的发展和危及人民的生命财产。本文利用差分干涉测量(DIn SAR)技术,以河北省廊坊市大城县为例,选用2016年6月至2016年11月期间3景RADARSAT-2数据,获取了该地区的地表形变信息。参考2009年该地区的地裂缝信息,对该地的地裂缝分布及走向进行了分析及预测,为生产单位和当地政府部门对地裂缝地震灾害的治理和预防提供了决策依据。
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（ DIn SAR）,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 DIn SAR,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.
