In this paper,the model of curtain type sheet pile wharf was established by general geotechnical FEA PLAXIS 3D,and the main parameters affecting the loading of sheet pile wharf structure were analyzed.The results show that:the internal force and displacement of the sheet pile structure are affected observably by the soil parameters；the soil behind the anchor structure can be reinforced in order to reduce the influence of the surcharge load on the sheet piles；the internal force caused by the residual water pressure should not be neglected,and the reliable measures should be used to decrease the residual water pressure；the construction procedure of the sheet pile wharf is important for the structural internal force；the effect of construction procedure should be considered in the analysis of internal force of structure which is conducive to ensure the safety of the structure.
