TThe non-linear analysis of the sheet-pile wall is given by geotechnical finite element software,PLAXIS, the deformation, the moment, the shear force distribution and the soil pressure distribution of the sheet pile are obtained, and the settlement and stress condition of foundation soil after the sheet pile wall under load are also analyzed. With the comparison of the elastic line method and the“m”method, the accuracy and reliability of PLAXIS is verified. The research shows that the finite element method of PLAXIS is reasonable.
