摘要

在Hodonín的住宅区测试了使用探地雷达（GPR）和Sentinel-1卫星合成孔径雷达（SAR）的程序，那里的底土严重减少，因此预制房屋出现了严重开裂。对现场的广泛地球物理研究提供了有关该地区活动断层的重要信息。为了证明它们并定义底土发生最大沉降的最活跃变形区（块体），使用了Sentinel-1 SAR卫星的处理干涉（InSAR）数据。地球物理数据和InSAR的联合评估结果不仅证实了检测到的变形，还通知了主要断层附近有沉降趋势的其他位置。将这些方法相结合来识别城市化地区的流离失所趋势是非常有效的。文章信息

Identification of ground instability in the housing estate complex based on georadar and satellite radar interferometry

Procedures of using ground penetrating radar (GPR) and Sentinel-1 satellite synthetic aperture radar (SAR) were tested in the area of housing estates in Hodonín, where there is an intensive decrease in the subsoil and thus a significant cracking of prefabricated houses. Extensive geophysical research of the site provided essential information about active faults in the area. To prove them and define the most active deformation zones (blocks), where the maximum settlement of the subsoil occurs, the processed interferometric (InSAR) data from the Sentinel-1 SAR satellite were used. Results from joint evaluation of geophysical data and InSAR not only confirmed detected deformations but also notified on other locations with tendencies to subsidence in the neighborhood of main faults. The combination of the methods to identify displacement tendencies in urbanized areas is very effective. ARTICLE INFO

期刊介绍： Acta geodynamica et geomaterialia (AGG) has been published by the Institute of Rock Structures and Mechanics, Czech Academy of Sciences since 2004, formerly known as Acta Montana published from the beginning of sixties till 2003. Approximately 40 articles per year in four issues are published, covering observations related to central Europe and new theoretical developments and interpretations in these disciplines. It is possible to publish occasionally research articles from other regions of the world, only if they present substantial advance in methodological or theoretical development with worldwide impact. The Board of Editors is international in representation.
