Experimentální analýza dynamických parametrů kolejového roštu / L'analyse expérimentale des paramtres dynamiques du rail grille

Podolník, Adam January 2014 (has links)
In terms of deciding on the appropriate use of the railway superstructure assemblies in both the recommendations arising from the theoretical analysis (modeling), as well as recommendations obtained under static and dynamic testing of the finished product play an important role. Such tests can then be applied in the laboratory or in the field. The thesis will be devoted to operational testing of selected track grid structures in situ. For measurement purposes an appropriate measuring point will be chosen and the methodology of measurement will be proposed. In terms of track geometry sections in curves will be selected. On the basis of tests carried out dynamic parameters of structures will be determined. To their evaluation suitable mathematical system will be chosen. It assumes the use of mathematical methods in time and frequency areas. In the thesis there will also be a comparison of the parameters of the tested structures. Based on the measurements it will be a source of recommendations for the practice.

Určení přetvoření železničního svršku / Deformation Surveying of Railway Track

Štrba, Peter January 2014 (has links)
The aim of this diploma thesis is to specify the displacement and deformations of the railway tracks axis on bridge structures in cities of Zábřeh na Moravě and Břeclav. The bridge structures covered have great dilatation distances, therefore it is necessary to monitor the movements of the railway tracks depending on climatic conditions. GPS methods have been used throughout the whole measurement and data processing. The result includes also a comparison of GPS and conventional methods. The result of the thesis is a detection of proven displacements. One of the goals of the thesis is the comparison of the displacements and the accuracy using the method chosen by author of the thesis and using classical geodetic methods.

Rekonstrukce železniční stanice Nedvědice / Upgrading of Nedvědice Railway Station

Rous, Petr January 2016 (has links)
The aim of the thesis is a reconstruction of Nedvědice railway station. The thesis contains modification of track geometry parameters of the railway, reconstruction of the railway superstructure and railway substructure. Platform with the platform edge height of 550 millimetres above the top of rail was designed. Design of a railway crossings according to valid regulations is other part of thesis. The thesis also include drainage system renovation.

Technologie rekonstrukce žst. Mikulášovice dolní nádraží / Railway Station Mikulášovice dolní nádraží Procedures of Works

Šardická, Klára January 2022 (has links)
This theses aims to propose two alternatives of optimised construction procedures for the reconstruction of the railway station Mikulášovice dolní nádraží. The reconstruction is based on the design provided by Metroprojekt Praha a.s. Each alternative describes suitable mechanization, coordination of works, including needed number of workers, coordination of the works and the total implentation cost analysis. As the thesis deals with reconstruction, it also considers substitute transportation plan. The details are summarized in extensive schedules. The two alernative are compared and evaluated.

Třetí kolej v úseku Blansko - Rájec-Jestřebí / The Third Track in Track Section Blansko - Rájec-Jestřebí

Šíp, Radek January 2019 (has links)
The task of the thesis is to propose the third track in track section Blansko - Rájec-Jestřebí and increasing line speed with maximum use of existing track body and grounds of SŽDC, s.o. Next is the design of the reconstruction of all engineering objects (bridges, runoffs, railway crossings and platforms). Additioning of the third track will cause extensive structural modifications at railway stations Blansko and Rájec-Jestřebí. Within the building will be verified construction of new railway stop Spešov.

Návrh vysokorychlostní tratě mezi Brnem a Znojmem / Design of the High Speed Track between Brno and Znojmo

Repko, Michal Unknown Date (has links)
The aim of this diploma thesis is to design a new track route of high speed line from Brno to Znojmo, specifically between the planned terminal of high speed line Unkovice and existing railway station Hrušovany nad Jevišovkou. The track is designed for a maximum speed of 250 km/h. The alignment and profile of the line were designed, including the design of the railway superstructure and track geometry parameters.
