To deepen the study of bearing characteristics of slope passive piles, based on the international general-purpose finite element software ABAQUS, this paper carries out a 3D simulation of slope passive pile. It is found that: The peak load is the main factor of pile displacement and pile bending moment, pile displacement and pile bending moment increase with the increment of the peak load; The influences of the peak load on the pile bending moment is mainly within the slope. The load on the pile top is favorable to reduce the pile shaft moment. The conclusion can be drawn that the ABAQUS finite element simulation is an effective method for studying the bearing behaviors of passive piles of bank slopes.
