This paper investigates liquefaction induced lateral spreading using a 2D Smoothed particle hydrodynamics (SPH) based numerical method in the framework of fluid dynamics. Owing to the fact that the induced displacement during lateral spread may reach several meters and the shear strain develops till 100%, a method which is essentially a Langrangian meshfree particle was developed to deal with large displacement. By assuming the liquefied subsoil to behave as a viscous fluid during earthquake shaking, a Bingham type model is used to model the liquefied soil. The ability of the method is checked using results from shaking table experiments to reproduce free surface shape, flow velocity and to investigate the relationship between time history of flow velocity, liquefied soil thickness and surface ground slope.
