Geodetic monitoring of the tubosider in Liberec under the ski slope F10
Buchar, Ondřej ; Jarůšek, Ladislav (referee) ; Kratochvíl, Richard (advisor)
This thesis describes a geodetic monitoring of a deformed steel structure tubosider in Liberec. There have been made periodic measurements of displacements and deformations of the object since 2015. Various interventions have been made in order to ensure a stability of the tunnel, which are also evaluated in this thesis. The results are graphs that describes shifts of the highest points in the tunnel. These values are further used by structural engineers and architects to suggest a solution.

GNSS Deformation Measurement of Railway Structure
Buday, Michal ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
The purpose of this thesis is to evaluate the train bridge shift using the satellite geodesy methods. Introductory part of the thesis is devoted to GNSS basis. The following part discribe work with commercial software Leica Geo Office. Results of calculations were transformed to local topocentric frame. In this frame were compared differencies between GNSS meassurment and classical terrestrial methods. Part of this thesis is to consider tropospheric refraction influence based on used tropospheric model. The end of this thesis is devoted to consider hypothesis that reference point which was considered as solid does not show trend of changing it's location. For this purpuse BERNESE GPS Software was used. GNSS meassurments were linked to the nearest points of permanent GNSS networks. Results are documented numerically and graphically.
