Abstract:As a kind of soil retaining support structure,sheet pile commonly used in the Dock, Lock and Foundation pit excavation projects,thus, there exists a sheet pile soil into depth design problem.The existing calculation method does not consider the wall between soil and the actual deformation condition and the earth pressure of the influence of size and distribution,there are some defects can not be neglected.In this paper, ANSYS finite element software are used in the numerical simulation of 3-d entity of the cantilevered sheet pile,Get the sheet pile displacement,and analysis the insert depth,the calculation results tally with the actual situation,This can provide the reliable reference data for designing and checking the insert depth of the cantilevered sheet pile structure.
