Surveying of Vertical Network with Use of Electronic Levelling.
Czíria, Kornél ; Sláma, Jiří (referee) ; Bureš, Jiří (advisor)
The work deals with building and followed surveying of two vertical networks with the method of geometric levelling using electronic level Leica Sprinter 150M with coded levelling rot. Due to the large difference in height between the points of the network corrections were introduced from the levelling-rot calibration at places of contact of the withdrawable parts of the levelling-rot. These corrections were calculated by the procedure, which was determined by the calibration test measurements. The final height of points of the network were adjusted by the method of least squares. Benefit of the calibration was analysed by comparing the results with the introduction and without introducing calibration corrections. Part of the work is also analysis of the accuracy and documentation of points of the vertical networks.

Deformation Measurement of Gagarin Bridge
Czíria, Kornél ; Vitula, Alexej (referee) ; Bureš, Jiří (advisor)
The work deals with a complex analysis of displacements and deformations of one bridge span of the railway bridge "Gagarin". The bridge structure was since 2009 annually measured. In addition to long-term monitoring of the bridge a 24-hour automatized monitoring was conducted in 2015 using robotic total station. The results of monitoring enables the analysis of displacements and deformations, analysis of measurement accuracy and also environmental influences on the structure - determination of the temperature dependence of deformations. Another part of the work is evaluating the long-term stability of the height reference frame that was used for geodetic epoch measuring of the bridge columns. The results of the work are the values of detected displacements and deformations, their graphical illustration, geometric interpretation and relevant characteristics of accuracy.
