Abstract
Pile foundations are widely applied in many projects.It is especially important to study the anti pulling bearing capacity of pile foundations from the viewpoint of security.According to the results of Plaxis 3D Foundation,the influence of pile amount,pile spacing and pile length on the vertical displacement of group piles under uplift loading is analyzed.The simulation shows that the pile length had no effect on the pile group effect coefficient.The smaller the pile spacing is,the bigger the soil displacement will be.The pile amount and pile spacing are the main factors influencing on the anti-pulling bearing capacity of the pile-group foundation.
