WebMar 27, 2024 · In this paper, a seismic forward-modeling method for fluid–solid coupled media (FSCM) with a transition layer is proposed. The second-order acoustic wave pressure equation and the second-order elastic wave displacement equation in heterogeneous media are used in the fluid and solid media, respectively. WebSeismic codes or earthquake codes are building codes designed to protect property and life in buildings in case of earthquakes. The need for such codes is reflected in the saying, …
