In order to discuss the stress and deformation characteristics of the corner segment in sheet pile wharfs，this paper studies a Z-type steel sheet pile wharf in Guangzhou Nansha Port. In addition，the paper adopts a hardening soil model with small strain as the soil constitutive model，establishes three spatial numerical models including the standard segment，the inner corner segment，and the outer corner segment of the sheet pile wharf by international large-scale finite element software，and analyzes the internal force and displacement distribution characteristics of the front wall，anchor tie，and anchor wall through comparison. The calculation results show that：1）The bending moment and displacement of the front wall，the tension force of the anchor tie，and the displacement of the anchor wall of the corner segment in Z-type steel sheet pile wharf are all smaller than those of the standard segment. 2）According to the calculation results of the standard segment，the design of the corner segment is conservative and can be optimized.
