摘要：In order to study the bearing characteristics on the composite foundation of group pile, the influences of variation of pile length, elastic modulus, spacing and cushion thickness on the bearing capacity for the composite foundation of group pile were investigated by finite element method. This paper presented the laws of the displacement and additional stress of pile with different parameters. The results showed that pile length, elastic modulus and spacing had great influence on the composite foundation of group pile; however, cushion thickness had less effective. Finally, this paper gave the optimal parameters, which provide a reference for practical engineering applications.
