| "This paper presents a numerical tool based on Smoothed Particles Hydrodynamics (SPH) to simulate the liquefaction induced ground flow around a pile foundation. The approach is formulated in the framework of fluid dynamics, assumed a Bingham type constitutive model and a phenomenological bilinear recovery constitutive model for the liquefied soil. The 1g shaking table experiment to measure the effect of liquefaction induced displacement on a pile foundation performed by Hamada et al. is used as a framework to perform the numerical simulations. The simulated results show that the approach offers promising perspectives in simulating the flow around the pile foundation, the distribution o the flow velocity as well as the stresses and shear strain field." |
