Abstract: Three-dimensional nonlinear elastic finite element method had been developed to study the bending behavior of the passive row piles subjected to surcharge nearby. The influence of the space between the row piles, foundation soft sublayer and the distance between surcharge and row piles on the bending behavior of the passive row piles was studied. The variety law of the bending moment and deflection was posted. Study showed that the positive bending moment of piles was 0.55 times pile-length in the vicinity of surcharge. There was biggish negative bending moment in the top of the piles. The negative bending moment varied from increasing to decreasing as surcharge increased. While surcharge increased to a certain value, the positive bending moment accelerated. The moment increased as the space of row piles. While there was soft sublayer in the ground, the negative moment decreased, moreover, the positive moment increased distinctly.

Key words: passive row piles, surcharge, three-dimensional finite elements, foundation soft sublayer
