| Abstract: | This paper analyzes the foundation isolation mechanism, including the seismic reflections from the layered soil interface, the scattering resulted from heterogeneities of foundation soil, dissipation energy by viscous of foundation soil, plastic deformation and friction of soil particles, and absorptions of seismic waves from liquefied soil layer. In the end, the paper summarizes that sand cushion and so on can be used as isolation damping material. |
