| 摘 要： | 通过采用小基线InSAR技术,将离散的DInSAR观测连接起来,获取吉林省九台营城矿区线性地表形变量,通过去除大气延迟相位计算非线性形变量,进而获取时间上连续的沉降场。经实地调查验证,InSAR计算结果较好地吻合了矿区开采范围和地表建筑物破坏情况。最后分析了营城矿区2012年沉降的分布和地表形变随时间的变化情况,揭示矿区沉降漏斗的分布、发展和演化规律。

| Abstract: | The Yingcheng mining linear surface deformation is obtained in Jiutai City,Jilin Province by using of small baseline InSAR technology to link discrete DInSAR observations.Then the nonlinear deformation is retrieved by removing atmospheric delay phase ,and temporally continuous subsidence field is obtained.Verified by field survey,InSAR results have well consistent with the scope of mining and the destruction of surface buildings.The distribution of the mining subsidence and the changes of surface deformation over time in 2012 is emphatically analyzed,which revealed the distribution of mining subsidence funnel,development and evolution. |
