Abstract: 3-D finite element method is used to analyze soil’s lateral deformation mode in the free field state in this paper. On the basis of that, lateral deformation and moment variable regularity of adjacent piles due to surcharge loads on the ground is explored, including different loads, loading distances, pile spacings and so on. Analytical results show that, piles’ deformation and moment will increase with the increase in loads, and piles will gradually become curved. If other conditions are the same, pile moment decreases quickly with the increase in piles’ stiffness, when the piles’ stiffness gradually become large, the pile will take on global displacement. Pile spacing and surcharge loads distance have important influence on pile moment and deformation. Pile moment and deformation will diminish with the augment in pile spacing and surcharge load distance.

Key words: passive pile, numerical analysis, surcharge loads, finite element
