In order to study the influence of the covered pile on the front wall，anchor wall and lever force performance of the sheet-piled wharf under seismic action，we carry out the dynamic finite element analysis of covered sheet-piled wharf of the 32# berth of Jingtang Port by ABAQUS software. The results show that the covered pile can significantly reduce the front wall bending moment and rod tension under the seismic action，and the influence on the force performance of the anchor wall is small. The thickness of the covered pile has a great impact on the rod tension and bending moment of the front wall below the mud surface elevation，and has a small effect on the front wall bending moment above the mud surface elevation and anchor wall bending moment. The front wall bending moment above the elevation of the mud surface line increases gradually with the increase of the spacing between the front wall and the covered pile，and the spacing between the front wall and the covered pile has no obvious effect on the front wall bending moment below the elevation of the mud surface line，anchor wall bending moment and rod tension. The length of the covered pile has less effect on the force performance of the front wall，anchor wall and lever under seismic action.
