Měření přetvoření mostní konstrukce a železničního svršku / Deformation Surveying of Bridge Construction and Railway Track

Staněk, Boleslav January 2014 (has links)
This diploma thesis deals with the phases measuring deformation of the bridge construction and railway superstructure on the bridge over the river Dyje in Breclav and its surroundings. The main goal was to determine the longitudinal displacements of the rail web and the bridge structure. The object of this thesis was also transverse displacements which have been caused mainly due to temperature changes. The introduction describes the location. The following section discusses the methodology terrestrial deformation measurements and calibrations selected surveying devices. Furthermore, there is stated the processing of measurements and the calculations. In conclusion, the thesis evaluates the longitudinal and transverse displacements, which are shown in the annexes.

Studie rekonstrukce železničních stanic Jindřichov na Moravě a Branná / Upgrading of Jindřichov na Moravě and Branná Railway Stations

Kubina, Jiří January 2014 (has links)
The master thesis "Upgrading of Jindřichov na Moravě and Branná Railway Stations" deals with designing new platforms that are suitable for people with reduced mobility in accordance with applicable laws and standards. Platforms with the platform edge height of 550 millimetres above the top of rail were designed. The speed limit was increased from the original 40 km/h up to 50 km/h. Moreover, the thesis design reconstruction of railway superstructure and railway substructure and deal with the drainage system.

Dynamická a akustická analýza konstrukcí železničního svršku / The analysis of the dynamic and acoustic parameters of the superstructure construction

Bačík, Jakub January 2015 (has links)
This diploma thesis is focused on operational testing of selected railway lines with different structures of railway superstructure. For the purposes of measuring were chosen suitable measuring sections on the rail corridor and was designed suitable measuring methodology. Dynamic and acoustic parameters of tested structures were determined on the basis of all tests, which were performed. Suitable mathematic method was chosen for evaluation of tests in time and frequency zone. Part of my work is also compare parameters of the tested structures and recommendations for practice.

Návrh zvýšení traťové rychlosti v úseku mezi žst. Hanušovice a žst. Bludov / Study of Speed Increasing of Hanušovice - Bludov Track Section

Lehnert, Jan January 2015 (has links)
In this thesis I propose increasing of the speed on the railway line No. 292 on the section žst.Bludov - žst. Hanušovice. It includes is complete design of horizontal and vertical ratios, eventually relocation of the track. Railway substructure is solved in selected sections. The thesis solves also editing of platforms and crossing structures.

Vývoj cenové hladiny v dodávkách železničních staveb / The Development of the Price Level in Railway Building

Maturová, Vladimíra January 2016 (has links)
This diploma thesis is describing the theme of price development of construction work on the railway superstructure. The result is meant as determination of technical-economic indicator which can be used in view of pricing mainly for public tenders as well as in the way of orientation at cost prices. The work is also engaged in production index for construction. The main meaning of this part is formed by comparing the dates of the Czech Statistical Office in the production of building and civil engineering in the Czech Republic between years of 2009 and 2015 with the production of railways constructions. As the railroad tracks are in corporate governance SŽDC state organization – whole planned construction works are controlled by conditions and rules of public tenders. After joining the Czech Republic into the European Union the requirements for optimal state of international transportation networks in their technical and social part had to be guaranteed. The thesis „The Development of the Price Level in Railway Deliveries“ includes topic of progressing of Czech economy, development of Czech and foreign markets and its influence on material deliveries and price fluctuations, pricing and costing. Because of main topic contains railway economy production there are given basic technical and technological information with application for Brno subregion.

Porovnání rekonstrukce žst. Březová nad Svitavou s výstavbou nové zastávky / A comparison between upgrading of the Březová nad Svitavou railway station and a new railway stop

Jelínková, Markéta January 2017 (has links)
The task of the thesis is to propose an adjustment to the railway station Březová nad Svitavou with regard to the introduction of the remote control of security device and explore the possibility of building a new railway stop that would be located closer to downtown. The aim is mutual comparison of elaborated variants. Work includes design of new platforms meet the conditions for safe access for people with limited mobility, next adjustment are adjustment of the geometric parameters of the track superstructure and substructure, including system of drainage station.

Rekonstrukce železniční stanice Veselí nad Moravou / Veseli Nad Moravou Station Reconstruction

Klar, Vít January 2017 (has links)
The subject of the Master's thesis is to design the redevelopment of the Veseli nad Moravou railway station. This renovation will include renewal of both, railway superstructure and substructure, including drainage system and new platform construcion proposal in order to meet current legislation regarding access of persons with reduced mibility and orientation skills. This thesis also deals with design of the track geometry compoments and geometry of set of switches at both heads of the railway station to fulfill the maximum train velocity demands at certain tracks. Last but not least, the rail track scheme of the station has been simplified.
