Geodetic Works in the Construction of a Subway Under the Railway Track
Adámať, Martin ; Bárta, Ladislav (referee) ; Bureš, Jiří (advisor)
Diploma thesis describes geodetic works in the construction of a subway under the railway track in Trenčín. Foundation for geodetic works in the construction is decree 300/2009 from the body of laws. The thesis describes these works in the order in which they were executed during the construction process. These works are: prepration of project documents, stake-out, control measurement, measurement of real building execution, quantification of executed building works, creation of real building execution documents. Part of the thesis describes the stake-out evaluation of each building phase and the evaluation of the building execution. The subway is a part of the railway modernization Nové Mesto nad Váhom – Púchov in city Trenčín.

Pavement Roughness Measurement with Use Geodetic Methods
Gašparík, Michal ; Bárta,, Ladislav (referee) ; Bureš, Jiří (advisor)
The issue of this diploma thesis is measurement of pavement roughness with an alternative means of data acquisition and evaluation by geodetic methods. In the beginning there is an overview of current state of actual roughness measurement methods. The main work is concerned with data acquisition with passive reflection of the laser rangefinder and laser scanner and standard deviations that arise in measuring on asphalt and concrete road surfaces. The aim of the work is to formulate the process of data acquisition, specification of standard deviations in the process of measuring, evaluation of pavement roughness according to ČSN 73 6175 standard, and their applicable graphic interpretation. Based on the analysis of accuracy of the methods applied, their usefulness is evaluated in comparison with the straightedge test.

Measuring the settlement of an apartment building
Kováč, Igor ; Vitula, Alexej (referee) ; Bureš, Jiří (advisor)
The subject of the bachelor’s thesis was the geodetic survey and processing of monitoring of vertical displacements and deformations of an apartment building. The measurement was performed by the method of precise levelling using hanging scales. Prior to surveying, tests were performed on the accuracy of the instrument readings depending on the length to the target and the differences between origins of the scales. The thesis processes three stages of measurement and deals with the process from measurement, through processing, to the production of graphic outputs. The largest value of the vertical displacement of the monitored point was -1.44 mm.

Measurement of vertical displacements and deformation of the bridge over the river Poprad
Horochonič, Maroš ; Hořejš, Marek (referee) ; Bureš, Jiří (advisor)
The content of this master´s thesis is a geodetic survey of vertical displacements and transformation of the supporting structure of the road bridge over the river Poprad in the 4th period with subsequent processing of measured data, calculation and evaluation of displacements with respect to previous stages. The work also includes the control of devices and aids used in the survey of the bridge construction and the behavior of the device's intentions during tempering. The result of this work are the values of the detected displacements and their graphical interpretation.

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.

Measurement of changes in the inclination of the Velký Kosíř lookout tower structure due to the influence of wind stress
Smetana, Jonáš ; Bárta, Ladislav (referee) ; Bureš, Jiří (advisor)
This thesis deals with the issue of displacements and deformations of building constructions. Specifically, it deals with changes in the inclination of the Velký Kosíř lookout tower structure due to wind stresses. The first part of the thesis deals with the theoretical description of the issue of displacements and deformations of buildings and measurement methods. The second part presents the testing of the geodetic method used for dynamic measurement. This involves setting up a total station in an automatic tracking mode and aiming a reflecting prism. The third part then deals with the actual measurement of the lookout tower Velký Kosíř, evaluation of the stage measurement, interpretation of the results and comparison of the methods used. These methods are represented by the polar method in a standard mode and the polar method in the mode of automatic tracking of the reflection prism and measurements of dynamic acceleration using accelerometer. The final objective is an evaluation of the inclinations under given wind conditions and the evaluation of the lookout tower inclination in the long term.

Geodetic Deformation Measurements of "Gagarin" Bridge.
Kováč, Michal ; Vitula, Alexej (referee) ; Bureš, Jiří (advisor)
The content of this master´s thesis is a geodetic measuring of movements and deformations of skeleton and underwork of „Gagarin“ railway bridge during the seventh period and processing of the data got. This was done by comparison of the movements according to the fifth and sixth period. The work includes also the calibration of appliance used. The results involve figures of the movements with their graphic interpretation and calibration sheets of the appliance.

Geodetic Works During Reconstruction of Road Crossing in Uherské Hradiště
Lovecký, Marek ; Sláma, Jiří (referee) ; Bureš, Jiří (advisor)
This thesis is engaged in geodetic works related to the increase of the capacity of the road II/497 and the modification of the intersection with the road I/55 in the town of Uherské Hradiště. The work is mostly focused on the field of the engineering geodesy. It resolves the issues from the alignment during the construction to the focus of the construction itself. Individual survey procedures are analyzed in the context of the prescribed deviations specified in the project documentation or ČSN. Geodetic documentation for the selected measurements is worked out.

Measurement of pavement surface roughness
Ďuriš, Samuel ; Bureš, Jiří (referee) ; Bárta, Ladislav (advisor)
The subject of the master thesis is to verify the possibility of application of geodetic methods to determine longitudinal and transverse pavement surface roughnesses. Geodetic techniques are compared to techniques specified in ČSN 73 6175. Subject of testing is absolute and relative accuracy of altitude measurement and accuracy of roughness parameter determination. As a result, the graphic interpretation of these parameters and deviations from reference values are presented in the current document. Practical use of the surveying methods is evaluated based on the application of the above mentioned techniques and the results of accuracy analysis.
