Thepaper used finite difference analysis software to carry out numerical simulation for sheet-pile wharf ,andanalyzedthe effect of soil body and barrier pile on the work behavior of sheet-pile wall. It simulated the stress state of sheet-pile wall when the parameter of soil body of sheet-pile wharfchanges.The result showed that the effect of soil's internal friction angle on the maximum negative moment of wall is the largest,the modulus of elasticity is the second and,the cohesive forceis the minimum. Theeffect of elasticity modulus on the maximum positive moment of wall is the largest,and then is thesoil's internal friction angle,and the effect of cohesive force on that appears ups and downs.Aimed at the influence of position of barrier pile on the wharf,it simulated the variation situation of the maxmum positive and negative moment of sheet-pile wharf when the distant of barrier pile to the front wall is one to ten meters.The result shows that when the distant of barrier pile to the front wall is two to five meters,the value of the bending moment of pile wall is at a lower range.
