Antoš, Filip ; Talich, Milan ; Glöckner, M. ; Böhm, Ondřej ; Soukup, Lubomír ; Havrlant, Jan ; Závrská, M. ; Šolc, Jakub
The methodology provides guidance for determining the vertical deflection of bridge structures using radar interferometry technology. The vertical deflection of bridges are primarily caused by stress during transit of vehicles. The deflections are simultaneously measured by radar throughout the length of the monitored structure. The measurement is continuous with a high sampling frequency (200 Hz) and with high precision (0.01 mm). It is believed the use of interferometric radar IBIS-S Italian manufacturer IDS. General recommendations and conclusions are valid for every kind of radar.
Determining of the deformation of the concrete dam Orlik using ground InSAR
Talich, Milan ; Glöckner, M. ; Böhm, Ondřej ; Antoš, Filip
GB InSAR technique plays an increasingly important role in determining the deformation of dams. The paper describes the use of GB InSAR technique for monitoring deformations of the Czech largest concrete dam Orlík on the Vltava river. After analyzing one month-long continuous measurement of the dam were detected non-linear movements. The relation between acting water level and resulting deformations were investigated in detail. The results confirm that GB InSAR technique is very suitable for monitoring deformations of this type of constructions. At the same time, the results may serve as a valuable source of data and information for further analysis in area of stability and for early warning systems.
