This study deals with assessing the behavior of a sheet pile wall by estimatingthe stresses and displacements of the sheet pile wall and surrounding soil throughoutthe different construction stages. The finite element method is used to carry out acomparison study to assess the effect of the soil nonlinearity on the behavior of sheetpile wall. The nonlinear hyperbolic model is used to represent both the soil andinterface behavior of soil-sheet pile wall system.The analysis of sheet pile wall was carried out using a nonlinear incrementalstress dependent finite element computer program capable of simulating the differentconstruction stages of the system. It was found that increasing excavation depthreduces both active and passive pressures below that calculated by Rankine theory andthat shear stresses concentrate around sheet pile wall and increase with increasingexcavation depth. It also noticed that adopting nonlinear soil properties leads to a moreeconomical design of the sheet pile walls.
