“…A nominal cohesion of 0.3 kPa is used for the sake of easy convergence [18]. Other parameters needed for the Mohr-Coulomb model such as the dilatancy angle is taken half of the frictional angle and the interfacial friction coefficient δ between wall-soil is taken 2/3 tan ϕ [5,11,14]. Figure 1 is a flowchart representing the research methodology followed in the present study.…”

“…One of the major assumptions made in the conventional design method is the use of triangular earth pressure distribution but in real practice, the earth pressure distribution is not triangular but much more complicated. Another drawback of the conventional design method is the use of constant earth pressure coefficient throughout the wall height for the calculation of earth pressure [5,6], which may result in the erroneous design of sheet pile wall using conventional design method.…”

In the present study two-dimensional finite element analysis has been carried out on cantilever sheet pile wall using ABAQUS/Standard software to study the effect of different friction angles and its related parameters such as dilation angle, the interfacial friction coefficient between soil-wall on earth pressure distribution, and wall deformation. From the results obtained, it is found that there is a significant decrease in wall deformation with an increase in the angle of internal friction and its related parameters. The earth pressure results obtained from the finite element analysis shared a unique relationship with that of a conventional method. Both the results showed similar linear behavior up to a certain percentage of wall height and then changed drastically in lower portions of the wall. This trend of behavior is seen in both active as well as in passive earth pressure distribution for all the frictional angle. Hence, after comparing the differences that exist in the results for both methods, from the analysis a new relationship between the earth pressure coefficients from a conventional method and the finite element method has been developed for both active and passive earth pressure on either side of the sheet pile wall. This relationship so derived can be used to compute more reasonable earth pressure distributions for a sheet pile wall without carrying out a numerical analysis with a minimal time of computation. And also the earth pressure coefficient calculated from this governing equation can serve as a quick reference for any decision regarding the design of the sheet pile wall.

“…The results and the model approximation are more closed to those provide by the real engineering application. A validated 3D FE numerical model based on field measurements to investigate the effects of pile length, sheet's location, pile's stiffness (including pile cross-sectional dimensions and Young's modulus), and soil properties were performed by Tang [25]. The results showed that the sheet's location could affect the formation of soil arching and the mechanism of earth pressure distribution for sheet pile walls.…”

In this study, a three-dimensional (3D) response of anchored sheet pile walls was investigated on double-anchored sheet pile system during soils excavation and tunnel construction sequence. This construction procedure is executed in areas front and adjacent the sheet pile walls. This paper focused on both areas of construction effects on the sheet piles. This numerical study aimed at the evaluation of the variation of bottom wall bending moment, top wall lateral and vertical displacements and anchor reactions forces exerted in the sheet piles. This paper also described the variation of the total anchor's reactions forces from the upper and lower anchors rows. A parametric effect such as upper and lower anchors rows distance was also performed to evaluate the variation of the wall bending moment, displacement and anchors total forces. The analysis results indicated that the reactions forces developed in the lower anchor rods are always higher than those developed in the upper anchor rods. The higher the distance between the upper and the bottom anchors the lower the displacement of the top wall in any stage of the construction. The minimum bottom walls bending moment is developed in the case where the distance between the anchor's rows divided by the wall height is 0.51. Positioning the upper anchors at 0.15 and the lower at 0.39 the wall height from the top wall will induce minimum top wall vertical displacement during soil excavation. This paper presents the results and findings of the parametric study performed.
