Due to their simplicity, analytical approaches based on the limit equilibrium approach have been used in the design of sheet pile walls for many years. However, due to a lack of understanding of the elastic behavior of the sheet pile wall and stress concentrations, some overestimations in values of maximum bending moment and anchor force may occur. These shortcomings have let an increment in the use of numerical models. In the present study, excavation work in the sand that has various fiction angles to be supported by a single anchored sheet pile wall was solved considering the ground water level and varying the anchor level from the soil surface. The effects of the solution method, soil friction angle, and anchor level on the embedment depth, anchor force, and maximum bending moment for sheet pile design are investigated using the free earth support and fixed earth support methods as analytical methods and the finite element method (FEM) as a numerical method. The Matlab R2015a program is used to execute analytical solution methods, while PLAXIS 2D V8.2 is used to do finite element (FE) analysis. The findings of embedment depth, anchor force, and maximum bending moment versus anchor level and friction angle of soil, null , are presented, illustrated, and discussed, in detail. As a consequence of the study, it is observed that the solution method, friction angle of soil, and anchor level have a significant effect on the design of the single anchored sheet pile wall and that the results of the fixed earth support method correlate better with the results of the FEM in comparison to the free earth support method. |
