Abstract
The dynamic compliance of different railway tracks on different layered soils have been calculated using a combined 6nite-element and boundary element method: conventional track on homogeneous soil with different stiffness, extreme, normal and inverse layering of the soil, plates in and on top of the soil (slab track on various soils), conventional track with elastic rail pads. The compliance functions of the track can easily be introduced into a coupled analysis of the vehicle-track-interaction to study the dynamic axle-loads and the dynamic diplacement amplitudes, which have also been measured at three different locations of a high speed line in Germany.
