Tram Type Influence on the Frequency Spectrum Character of the Subsoil Dynamic Response

This article deals with the results of the experimental seismic measurement using a standard seismic in situ station on a rock mass where the influence of the type of the trams passing on the frequency spectrum characteristics, the bandwidth and the maximum peaks was monitored. The goal of presented experimental measurement was to verify whether it is possible to find common patterns for individual types of tram cars in the frequency spectra using standard equipment for seismic measurements. The results show that in the spectrums certain characteristics can be traced, which are common to both a particular type of tram and a common group of tram types historically or structurally derived from each other. Streszczenie. W artykule przedstawiono badania sejsmiczne związane z przejazdem różnych typów tramwajów. Przedstawiono charakterystyki widmowe oraz monitorowano pasmo częstotliwości. Ekspeyment wykazał że każdy z pojazdów jak również każdy typ pojazdu ma typową dla siebie charakterystykę sejsmiczną. Badania sejsmicznych charaterystyk widmowych różnych typów pojazdów szynowych
