Short summary
In current marine seismic engineering research, the influence of overlying-seawater weight and soft soil on seabed ground motion is often ignored, which leads to unsafe seismic design. In this paper, four representative calculation models are constructed, and the finite-element method is used for numerical simulation analysis in order to evaluate the amplification effect of overlying seawater and the seafloor soft soil layer on ground motion.
