This paper presents a three-dimensional finite difference numerical analysis of cap-pile system under earthquake. The deformation law of the cap-pile system and the variation characteristics of the axial force and moment of the pile are obtained. Under the action of earthquake, the settlement of the cap is increasing, and finally did not retrace, while the axial force and bending moment of the pile, present the trend of increasing first and then reducing, and the withdrawal efforts are great. The force and displacement are not completely corresponding relationship under the action of the earthquake. The moment of the pile swings at 0 o’clock under earthquake.
