Originální abstrakt

The paper is devoted to the operational measurement of two selected structures of railway superstructure, fixed track and a classical structure with ballast bed. Suitable measuring stations on corridor lines were selected and the corresponding measurement methodology was designed for the measurement purposes. Based on the response of tested structures to a moving load, i.e. the train set, the monitored parameters were obtained. Acoustic parameters of the two tested structures were determined based on the tests carried out. An appropriate mathematical apparatus was selected for the evaluation of the measurement, based on the use of mathematical methods in time and frequency domains. This article contains a comparison of parameters of the tested structures and recommendations for practice.
