Dynamické zatížení v okolí tramvajových výhybek

Abstract

This bachelor thesis deals with the degree of dynamic load in the vicinity of tram switches. This problem was evaluated on the basis of measured in-situ data in a perpendicular profile to the switch tongue. The measurements were performed at five locations with a digital three-component recording apparatus BRS-32. Processing of measured values was performed in the BR Monitor program. Graphs of vibrations in the rock environment from the source of the seismic impulse as a function of distance were created from the values. Subsequently, attenuation curves were created from these points.

Part of the work is a presentation of the tram fleet of the city of Ostrava. A geological survey was carried out at the investigated localities, and subsequently 3D models and sections of the area of interest were made in the RockWorks program.
