Abstract
In this paper, the numerical analysis focused on the liquefaction of body of embankment was performed with the three-phase (soil, water, and air) coupled analysis based on porous media theory. In this technique, the conventional constitutive model for describing the cyclic behavior of unsaturated soil was employed. From the numerical simulations about the shaking table test, it was revealed that the simulation could reproduce the experimental results well and that the proper consideration of the unsaturated condition is important. Furthermore, the series of simulations indicated that the existing embankment would be deformed beyond the limitation of the settlement required in design.
