Numerical simulations of a centrifuge test, in which dissipation patterns, lateral spreading, and shear strain localization were measured and recorded, are performed for validation of the numerical modeling approach and insight on the deformation mechanisms. The constitutive model calibration process is performed based on available laboratory data and is described in detail. The model container and construction sequence are simulated to provide good approximations of the boundary conditions and initial stress distributions. Two approaches for simulating successive shaking events are presented and compared. The key observations and mechanisms from the centrifuge test, namely (1) the dynamic response and onset of liquefaction, (2) the amount and pattern of surface deformation, (3) the patterns of pore pressure dissipation and void ratio redistribution, and (4) the difference in response between a sand profile treated and not treated with liquefaction drains, are all reasonably captured and bounded by the simulations.
