The generalized finite element models of anchorless，single-anchored，and counterweight sheet-pile wharves are built separately，and a 100，000-ton sheet-pile wharf is used as a prototype for numerical analysis. The results indicate that the maximum horizontal displacement of the counterweight sheet pile is 1/13 of the anchorless sheet pile and 1/2 of the single-anchored sheet pile. The soil pressure distribution of the anchorless sheet pile sees a sudden change in the soil entry section，and that of the single-anchored sheet pile encounters the same behind the wall above the soil surface，while that of the counterweight sheet pile is relatively smooth behind the wall and in front of the wall. For anchorless and single-anchored sheet piles，the distributions of bending moment and shear force are reversed many times，especially for the anchorless sheet pile，while in the case of the counterweight sheep pile，except for the sudden change in bending moment at the counterweight table，the distributions of bending moment and shear force in other positions are relatively smooth. In the case analysis of the project，the horizontal displacement and bending moment of the counterweight sheet pile are within the normal range. Moreover，the counterweight structure does not require the setup of the combined structure such as the anchor system and the rear cast-in-place pile，featuring many advantages such as strong site adaptability，simple construction，and low construction costs. It has strong application value in sheet-pile wharves.
