A fully-coupled effective stress method of analysis incorporating an elastic-plastic constitutive model specifically designed for modelling sand behaviour was used to numerically simulate shake table experiments on piles in laterally spreading soils. Details of numerical procedures including modelling of stress-strain behaviour of sand, identification of the initial stress state and 3-D dynamic analysis of the soil-pile system are presented in this paper. Primary objective of the simulation was to assess the accuracy of the 3-D analysis in predicting the response of the pile foundation and to identify parameters that are critically important for successful numerical simulation of lateral spreading experiments. The computed response is compared to that measured in the test and key features of the behaviour of the ground, foundation piles and sheet pile wall are discussed.
