https://doi.org/10.4467/2353737XCT.16.216.5965The study presents a selection of free-field vibration measurement results (the horizontal component x vibration is perpendicular to the axis of the track) in the ground surface layer, in one of the three measuring polygons. Pendolino, InterCity and InterRegio trains, excited free-field vibrations. Results for speeds of 120 and 160 km/h were analysed to have comparison that is more tangible.

https://doi.org/10.4467/2353737XCT.17.005.6102The paper deals with the transmission of mine-induced vibrations in the LGC region from the ground to the foundations of typical buildings. The simple, easy-to-use models have been proposed for the determination of the differences (relations) between ground and foundation acceleration response spectra. Experimentally obtained acceleration response spectra from vibrations occurring simultaneously on the ground near the building and the building foundation were the basis for the verification of the accuracy of the proposed models.

https://doi.org/10.4467/2353737XCT.17.007.6104The objective of the paper was to conduct dynamic measurements of free-field vibrations in three profiles and establish decay relations of propagating vibrations. The sources of vibrations were passages of the Pendolino train with dedicated speeds from 40 to 293 km/h. In each profile, soil properties tests were carried out. Based on the data for a few selected speeds of the Pendolino train’s passages, the Vibration Reduction Coefficients (VRC) were determined at selected points. The paper is also focused on the analysis of vibrations of the selected one-storey masonry residential building located in the vicinity of one of the profiles and their evaluation of the harmfulness on the building structure using standard scales of dynamic influence.
