为了深入分析地表沉降,采用D-In SAR技术对矿区高速公路及附近开采区沉陷进行监测,通过GIS叠置分析,得到了监测区的下沉范围及高速公路变形量大小,分析了高速公路的安全性,与常规地面实测结果比较,证明了In SAR监测的精度及可靠性。
In order to thoroughly analyze the deformation of expressway,D- In SAR technology were used to monitor the settlement of an expressway and mining area around,and through GIS overlay analysis,the monitoring area subsidence range and deformation of expressway were obtained,the expressway safety was analyzed,and compared with the conventional ground test results,the accuracy and reliability of In SAR monitoring were verified.
