Track vibration is one of the main sources of railway rolling noise. The resilient components in the railway foundation such as the pad and ballast have significant effects on the track vibration. Usually, their parameters vary with load and frequency. The wheel load of a train causes local deformat
The propagation of waves through homogeneous or layered soil is calculated based on half-space theory. The moving dynamic loads of a train are approximated by fixed dynamic loads and the wave field can be calculated if the spectrum of the dynamic train loads is known. In addition to this dynamic wav
Based on the Betti-Rayleigh Dynamic Reciprocal Theorem, the reciprocal property of the Green's functions is demonstrated, on the basis of which the analytical solution of soil vibration subjected to moving loads is derived. By application of the Betti-Rayleigh Dynamic Reciprocal Theorem, the moving
