| 摘 要： | 采用TerraSAR-X数据,运用GAMMA软件进行D-INSAR二轨法数据处理,获得某矿区工作面地表下沉数据,绘制出相应的下沉盆地,对比实测数据,研究得出:矿区D-INSAR监测下沉值曲线与水准实测下沉值曲线在走势上一致,得到了两者差值和点位距离地表最大下沉点距离之间的变化规律;尝试性的给出了改正公式;改正效果满足地表形变监测的需要。

| Abstract: | By using TerraSAR-X data,it carried out the data processing of D-INSAR two-track method with GAMMA software,and got the surface subsidence data of the working face in a mining area.Then the subsidence basin was drawn,compared with the measured data,the research obtained that the trends of mining area D-INSAR monitoring subsidence value curve and level measured subsidence value curve were consistent,then obtained the variation law of their difference value and the distance between the point position and maximum surface subsidence point.It gave the correction formula tentatively,the results met the need of surface deformation monitoring. |
