The article discusses the synthesis of seismograms for a multi-scale transversely isotropic (TI) saturated layered half-space subjected to seismic dislocation sources. The authors propose a revised stiffness matrix method to overcome the challenges of simulating wave propagation in multi-scale half-spaces with varying layer thickness and velocity. The method involves transforming the governing equations of motion, imposing the seismic source as body forces, and obtaining a global stiffness matrix by assembling each layer's exact stiffness matrix. The accuracy of the method is verified through comparisons with published literature, and the effects of superficial layers on ground motion are illustrated through numerical examples. The proposed method provides a fast and accurate way to synthesize seismograms in complex geological structures. [Extracted from the article] |
