The calculation of sheet pile wharf is mainly based on the current code for design of sheet pile wharf.In order to improve the calculation accuracy,this paper takes a practical project as an example and uses the other two improved calculation methods to calculate the structure of the sheet pile wharf.The similarities and differences of the calculation methods are compared,and the results of each method are analyzed.The most important parameter of the elastic foundation beam method is the proportion coefficient m of the horizontal ground reaction coefficient which increases with the depth.It is suggested to determine the m value according to the cohesion c and the internal friction angle φ.
