| 摘 要： | 南京河西地区属近代长江退移形成的河漫滩地,固结沉降一直持续发展.提出利用短基线DInSAR新方法监测长江漫滩区大面积地表沉降的新思路,利用多幅差分干涉图序列进行时间序列分析,获取大面积地表沉降的演变过程.南京河西长江漫滩区1996年到2000年短基线DInSAR法沉降监测试验结果表明,该区大部分存在不同程度地面沉降,最大累积沉降量达12 cm.与精密水准检测结果在空间分布上的一致性证明了该方法的正确性.

| Abstract: | The west areaof Nanjing Qinhuai River belong to flood land formed by retrogressive evolution of Yangtze River in modern times and its consolidation settlement has been continuously developing.In this paper,anew subsidence monitoring method of short baseline DInSAR,which used anumber of differential interferograms to generate displacement time series,was proposed;the strong point of the new method is that it can get the surface subsidence evolution process in alarge areaof land.The settlement monitoring resu... |
