Three dimensional finite difference simulation of liquefaction phenomenon
Developing an appropriate simulation model for liquefaction phenomenon remains a challenging issue in the geotechnical earthquake engineering. In this paper, via FLAC3D, a 3D finite-difference model was developed in order to simulate the liquefaction phenomenon. In this model, the three-dimensional type of Finn constitutive model has been developed for liquefaction simulation. The material constants in the Finn constitutive model reasoned by contrasting the FLAC3D results with the experimental centrifuge tests such as VELACS, and some adjustments were made before a match was obtained. In this way, the accuracy of the developed model in the liquefaction simulation has been improved. Also, using the validated model, some parametric analyses, including the effect of friction angle and relative density of the liquefiable soil on the liquefaction resistance of loose sandy soil, were performed and discussed.
