Using three-dimensional finite element analysis in time domain to model railway-induced ground vibrations
The finite element analysis is used to assess the ground-borne vibrations. Time domain simulation is preferred for reducing the model size. Lysmer and Kuhlemeyer absorbing boundary conditions are analysed. Structural vibrations are calculated for realistic cases. A mesh tool is presented to automatically add infinite elements in ABAQUS model.
