However, behaviors of piles in lateral spreading due to soil liquefaction is particular important and complicated. This paper researched responses of pile foundation in lateral spread based on a three dimensional soil–water coupled dynamic analysis. At first, numerical model of accordance with simulation to Abdoun et al. (2003) was to use physical single pile test in inclined ground of 50g centrifuge test. This part of study focused on responses of the single pile in two and three layered inclined ground with two liquefaction strength. And then, this study set up a model to simulate lateral responses on group pile foundation, referred to Uzuoka et al. (2008). Responses of the group piled foundation with some change of the height of footing, length of pile and in the layered of ground with different liquefaction strengths was discussed and compared with the one of single pile.
