Testing of automatic measurement system
Hromková, Zuzana ; Vondrák, Jiří (referee) ; Machotka, Radovan (advisor)
The thesis deals with testing of the automatic measurement system, namely of the system for monitoring civil engineering structures Trimble 4D Control. A summary of the basic principles of deformation monitor is given at the beginning of the study and is followed by an overview of the system´s structure. The activities carried out under the pilot project (beginning with the installation of the system and finishing by the evaluation of the measured data) are described. The project demonstrated by the functionality, reliability and usability of the systam for monitoring of the structures.

Possibilities of precise determining of deformation and vertical deflection of structures using ground radar interferometry
Talich, Milan
The contactless determination of deformations and deflections of structures with accuracy up to 0.01 mm in real time can also be used in practice the technology of ground based radar interferometry. It is also possible in real time to capture oscillations of the object with a frequency up to 100 Hz. Deformations can be determine simultaneously in multiple places of the object, for example a bridge structure at points distributed on the bridge deck at intervals of one or more meters. This allows to obtain both overall and detailed information about the behavior of the structure during the dynamic loading. In addition to the necessary principles are given practical examples.

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.

Precise monitoring vertical deflection of bridge structures using method of ground radar interferometry
Talich, Milan
The contactless determination of vertical deformations of bridge structures with accuracy up to 0.01 mm in real time can also be used in practice the technology of ground based radar interferometry. It is also possible in real time to capture oscillations of the object with a frequency up to 50 Hz. Deformations can be determine simultaneously in multiple places of the object, for example a bridge structure at points distributed on the bridge deck at intervals of one or more meters. This allows to obtain both overall and detailed information about the behavior of the structure during the dynamic load and monitoring the impact of movements either individual vehicles or groups. In addition to the necessary theory are given practical examples.
