Centrifuge modeling on shallow foundation subjected to reverse faulting

A series of centrifuge modeling on the free field and on a shallow foundation rested on the surface both subjected to reverse faulting with a dip angle of 60° at an acceleration of 80 g was conducted to evaluate the evolution of the surface deformation profile, the subsurface deformation pattern, the development of fault trace, and the soil-shallow foundation interaction. The magnitude of foundation bearing pressure and the location of foundation relative to the reverse fault rupture trace strongly affect the profiles of surface deformation, the fault rupture propagation traces, and the location of emergence of rupture line on the surface. The heavier foundation bearing pressure (87.2 kPa) is capable to divert the fault rupture traces and to stop the fault rupture traces emerging under the foundation.
