Constitutive model and its application of flow deformation induced by liquefied sand

In this paper, the experimental model is introduced. And then the model is extended to three dimensional equations, and formulated into a finite-difference algorithm (FLAC3D) to obtain the new model named Liquefy Model. The Liquefy Model gives an accurate description of the liquefied phenomena. The simplified method of large flow deformation induced by liquefied sand is proposed based on Liquefy model in FLAC3D framework.
