摘要: In this work, we investigate elastic wave propagation in complex geological media that exhibit material inhomogeneity in the form of depth-dependent material parameters and heterogeneity in the lateral direction. In addition, we consider a layered structure with non-parallel interfaces, free-surface relief, plus the presence of different type of discontinuities such as interface and/or internal cracks. The seismic load comprises incident, time-harmonic pressure (P) and vertically polarized shear (SV) waves, thus covering the plane strain case …
