Scatteing of seismic waves by crack in multi-layered geological regions II. Numerical results

摘要

The mechanical model for plane strain, time-harmonic seismic wave propagation problems in cracked, multi-layered geological regions with surface topography and non-parallel interfaces was described in the first part of this work. Here, this model is used to investigate the response of such a region to the presence of traveling elastic waves generated by a seismic source. The computational methodology that was developed in the first part is based on a combination of both the regular(displacement-based)and the hypersingular(traction-based) Boundary Integral Equation Method(BIEM).
