Rail induced wave propagation in soil facing sloping rock
Other conference contribution, 2003

The paper examines solid wave propagation in the soil underneath a high speed train. The shortcomings of the finite element method at parts of the boundary are compensated for by the usage of a hybrid method including both regular elements and scaled boundary finite elements. The technique is applied to a rail section facing sloping rock, much like the sea facing the shore. Simulations will be conducted at different train speeds in order to examine whether a breakthrough resembling a “sonic boom” effect is detectable. Amplitudes are expected to be higher when going above the soil’s natural wave velocity.
