Abstract

In this study, dynamic centrifuge model tests in the 50 g field were conducted to investigate the soil-structure behavior in liquefiable sand during large earthquakes. A miniature model of deep mixing walls (DMWs) was made of soil-cement with an unconfined compressive strength of ~ 4,000 kPa to investigate the behavior/toughness of DMWs after yield and failure, regarding their seismic performance. Numerical simulations were conducted to reproduce the experimental behavior. The simulation code MuDIAN was used with the YT model as a soil constitutive equation. The behavior of the excess pore water pressure ratio, soil, and building acceleration were able to replicate the experimental behavior in general, employing soil parameters determined from the laboratory element experiments.
