摘要
以某市城市轨道交通2号线穿采空区段为工程背景,采用差分干涉测量(D-InSAR)技术对研究区域进行雷达遥感监测分析,得到该区域2007-2011年不同时间段的沉降量(精度达到cm级)以及年平均沉降速率,同时结合2012-2013年间的最新合成孔径雷达SAR数据验证比较最近两年的沉降量及沉降速率。基于沉降监测成果,分析对两种方案通过该采空区及沉陷区的可行性进行专题研究,从而为2号线线路方案选择提供技术支撑。
Based on urban rail transit line 2under the engineering background of mining area section,this paper uses differential interferometry（D-InSAR）technology to analyze radar remote sensing monitoring of the study area,thus gets different times settlement level precision in this area from2007 to 2011and the annual average sedimentation rate.At the mean time,it compares the latest two-year subsidence and sedimentation rate with reference to synthetic aperture radar SAR data（2012―2013）.Based on settlement monitoring results,this paper analyzes the feasibility of goaf and subsidence areas under the two kinds of schemes and provides technical support to line 2scheme selection.
