摘要
采用差分雷达干涉测量技术,利用2017年2月19日—5月29日间的5景高分辨率TSX/TanDEM雷达影像,开展长双公路段路基形变探测研究,并结合研究区预埋位移传感器数据,进行路基冻胀融沉形变规律分析.结果表明,基于DInSAR干涉测量获取的公路路基形变结果与冻胀计结果,在时序形变趋势上具有较好的一致性,DInSAR技术在季冻区公路冻胀融沉形变监测方面具有较好的应用效果.
Using the 5 TSX/TanDEM high resolution radar images during 2017.02.29 to 2017.05.29,the research of double long highway subgrade deformation detection was carried out with the technique of differential Interferometric synthetic aperture radar(DInSAR).And the deformation law of frost heaving and thaw settlement was analyzed,combining with the data of embedded displacement sensor in survey region.The results show that the highway subgrade deformation results based on DInSAR interferometry are consistent with the results from the frost heaving meter on the deformation trend sequence.DInSAR technology using in Frost heaving and deformation monitoring of subgrade in seasonal frozen soil zone has a good application effect.
