Design of the Route of HSL Rakvice - Kuty
Komora, Andrej ; Janoušek, Jan (referee) ; Říha, Tomáš (advisor)
The goal of the bachelor’s thesis is to design a high-speed railway line between Rakvice and Kúty (Slovakia). The route serves as an extension of the High-Speed Rail Jižní Morava (South Moravia) towards Slovakia, which is part of the TEN-T Core Network. The studied section begins near the village of Rakvice. The proposal has been developed in a single main variant. The design speed is 350 km/h, and the speed of the slowest train is 180 km/h.

Route Study of the Track Modernization Ceske Budejovice - Horni Dvoriste, 1st part
Andrlová, Monika ; Vukušič, Ivan (referee) ; Říha, Tomáš (advisor)
The aim of the bachelor´s thesis was to design a new route of the railway route Ceske Budejovice – Horni Dvoriste in the section Roudne u Ceske Budejovice – Netrebice. The design of the railway route was carried out for different line speeds with the aim of finding a suitable compromise between the maximum acceleration of travel times and the use of the existing earth body. Subsequently, the most suitable variant eas evaluated and is elaborated in the study details.

Track Layout Relaying Design in Section Lestina u Svetle - Golcuv Jenikov
Čechová, Tereza ; Hoza, Miroslav (referee) ; Říha, Tomáš (advisor)
The aim of the bachelor thesis was to design the relocation of the railway line Havlíčkův Brod – Kolín in the section Leština u Světlé – Golčův Jeníkov. The section was to be prepared as an alternative for different line speeds with the aim of finding a compromise between maximum acceleration of journey times and the use of the existing earthwork. The chosen most advantageous option will be justified and elaborated in the details of the study.

Moravske Branice - Oslavany Track Speed Increase
Hrdlička, Šimon ; Křemen, Tomáš (referee) ; Říha, Tomáš (advisor)
The bachelor's thesis deals with the increase of a track speed in the section Moravske Branice – Oslavany. The thesis attempts to obtain a speed increase by modifying the existing geometric parameters of the track in the scope of the regular maintenance, in some cases even more thorough, yet still not that costly. The assessment of geometric parameters of the track is done according to the standard CSN 73 6360-1. It is also assessed whether the individual railway crossings meet the conditions for the track speed increase. Part of the thesis is also the design of speed for vehicles with a permitted cant deficiency of 130 mm.

Boskovice Connection Study
Jung, Jiří ; Sobotka, Lukáš (referee) ; Říha, Tomáš (advisor)
The thesis solves the design of the railroad called Boskovice connection, which is a line allowing direct connection for trains from Brno to Boskovice outside the railway station Skalice nad Svitavou. In the course of the work, the route of the connection is planned, including the connection to the Rajec-Jestrebi – Skalice nad Svitavou and Skalice nad Svitavou – Boskovice track section.

Spatial materials for additive manufacturing in civil engineering
Říha, Tomáš ; Apeltauer, Tomáš (referee) ; Podroužek, Jan (advisor)
The bachelor thesis deals with additive manufacturing in the construction industry and with materials used in this field. The first part of the thesis defines the 3D printing, briefly describes the history of this progressive technology and gives an overview of the used methods and technologies. The printing methods are divided according to the physical state of the basic material used for printing. The next part of the thesis presents the possible use of additive manufacturing in the construction industry and an overview of realized projects. Finally, at the end of the theoretical part are introduced materials applicable to additive manufacturing in the construction industry and is defined the concept of spatial materials. Spatial materials are a relatively new term, which is not yet in the literature sufficiently defined. These materials can be used for an application in a space where the structure and the position of their particles can be optimized. They can be applied for the creation of 2D filling structures, which are more useful for geometrically simple and simply loaded constructions. It is preferable to use spatial materials to create 3D structures that are designed to fill numerically optimized structures. These structures are based on the principle of double curvature and on a triply-periodic minimum surface (TPMS). In the practical part of the thesis was created the design of building block filled with 3D gyroid structure, designed for prefabrication by using additive manufacturing in the factory or at the site of construction. This proposal reflects the increasing demand for easy individualization of constructions and building elements. Especially, the demand for the creation of structures and shapes which are topologically optimized with a customized appearance and sufficient strength, all at the customer's request.
