摘要
利用InSAR技术对广东省英德市英城街道地表形变进行监测,结合地质勘查对地表沉降成因机理进行分析.结果表明,InSAR技术可以实现对该地区地表形变的快速监测,地表沉降是由覆盖层厚度、下伏岩层岩溶发育以及水动力条件共同作用所致.InSAR技术为地质灾害监测提供了一种可靠手段.
Abstract
InSAR technology was used to monitor the surface deformation of Yingcheng Street in Yingde City,Guangdong Province,and the cause mechanism of land subsidence was analyzed in combination with geological exploration.The results showed that InSAR technology can realize rapid monitoring of surface deformation in this area.Surface subsidence is caused by the combined effects of overburden thickness,karst development of underlying strata and hydrodynamic conditions.InSAR technology provided a reliable means for geological disaster monitoring.
