In order to effectively control vibration related problems, the development of a reliable vibration monitoring system and the proper assessment of attenuation characteristics of various vibrations are essential. Various ground vibrations caused by train loading, blasting, friction pile driving and hydraulic hammer compaction were measured using 3D geophones inside of the borehole as well as on ...

Vibrations of a wind turbine have a negative impact on its performance. Mitigating this undesirable impact requires knowledge of the relationship between the vibrations and other wind turbine parameters that could be potentially modified. Three approaches for ranking the impact importance of measurable turbine parameters on the vibrations of the drive train and the tower are discussed. They inc...

We analyze in detail the seismic vibrations generated by trains, measured at distance from the track with high sensitivity broadband sensors installed for the AlpArray project. The geometrical restrictions of the network resulted in a number of instruments deployed in the vicinity of railway lines. On seismic stations within 1.5 km of a railway, we observe characteristic seismic signals that we...

To predict and control the train-induced vibration in depot buildings, a case study of Tianjin Metro, Line 5, was conducted. The platform has been constructed is use, construction over-track buildings not completed. Firstly, an situ measurement performed to obtain train loads validate numerical model. Secondly, finite element model track–soil–depot structure established. simplified as series tw...

In the present paper, the theory of generation of ground vibrations by moving train is considered. The theory takes into account contribution of each sleeper of the track subjected to the action of all wheel axles. Mechanical properties of the track and parameters of train and soil (including static contact nonlinearity of track-soil system) are taken into account. It is shown that generated gr...
