Evaluation of the rail pad stiffness
Šardická, Klára ; Pazdera, Luboš (referee) ; Smutný, Jaroslav (advisor)
Rail pads are part of baseplate and baseplateless fastening system. It is a flexible element that is used primarily to reduce the negative effects of dynamic stress, reduce noise and vibration. This thesis deals with laboratory measurement of low-frequency dynamic stiffness at 5 Hz, static stiffness according to ČSN and static stiffness according to OTP of rail pads. The aim is to carry out and evaluate the measurements of samples supplied by different manufacturers and to compare them according to the variance of the resulting stiffnesses. Evaluate the stiffness of used rubber pads and compare with the results of new samples. Further, this thesis deals with the factors that the measurement itself and its results could influence.

Railway Station Mikulášovice dolní nádraží Procedures of Works
Šardická, Klára ; Wrana, Radim (referee) ; Svoboda, Richard (advisor)
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.
