In order to study the soil deformation influenced by adjacent piles when subjected to large area loading, 3D finite element method was adopted to investigate the pile-soil interaction in the Beilun power station preloading project. By considering the pile restriction to soil deformation emphatically, the numerical simulation analysis showed that the soil settlement decreased with piles existed, while the soil lateral deformation increased around the piles in a certain range close to the ground. Moreover, the bending moment of pile body and the stress of the steel embedded in the pile were calculated to examine the stability of break wall pile foundation under loading. An empirical equation of maximum bending moment was obtained for piles with caps. Good agreement of calculated results with the measured data showed that this work can be used to support the relative design and construction.
