摘      要：A simple and fast prediction scheme is presented for train-induced ground and building *** models such as(one-dimensional)transfer matrices are used for the vehicle–track–soil interaction and for the building–soil *** wave propagation through layered soils is approximated by a frequency-dependent homogeneous *** prediction is divided into the parts“emission(excitation by railway traffic),“transmission(wave propagation through the soil)and“immission(transfer into a building).The link between the modules is made by the excitation force between emission and transmission,and by the free-field vibration between transmission and *** formula for the simple vehicle–track,soil and building models are given in this *** behaviour of the models is demonstrated by typical examples,including the mitigation of train vibrations by elastic track elements,the low-and high-frequency cut-offs characteristic for layered soils,and the interacting soil,wall and floor resonances of multi-storey *** is shown that the results of the simple prediction models can well represent the behaviour of the more time-consuming detailed models,the finite-element boundary-element models of the track,the wavenumber integrals for the soil and the three-dimensional finite-element models of the *** addition,measurement examples are given for each part of the prediction,confirming that the methods provide reasonable *** the prediction models are fast in calculation,many predictions can be done,for example to assess the environmental effect along a new railway *** simple models have the additional advantage that the user needs to know only a minimum of ***,the prediction is fast and user-friendly,but also theoretically and experimentally well-founded.
