Numerical analysis of anchored sheet pile walls

Abstract EN

Anchored sheet pile walls are used to restrain excavation when the depth of the excavation exceeds about 6 m.

In this paper, the influence of some parameters on anchored sheet pile walls was studied.

The parameters are: anchor inclination with the horizontal ground, the number of anchors (one -row, or more), the cohesion of soil, and angle of internal friction of the backfill soil.

The previous parameters affect soil behavior, wall bending moments, and wall displacement.

Numerical analysis of the anchored sheet pile walls was implemented using a finite element program GEO5.

The results of the analysis indicated that the optimum angle of anchor inclination is 25 degrees to reduce the horizontal displacement at the top of the wall and maximum bending moment.

Variation of the angle of internal friction has a significant effect on the wall.

As the friction angle increases, the maximum displacement and the internal forces decrease.

As the cohesion of soil increases, the maximum bending moment, shear force, and wall displacement decreases.

Increasing the number of anchors decreases the maximum bending moment, wall displacement, and increases the maximum shear force
