Abstract
Finite element simulations were carried out to investigate three-dimensional (3D) active earth pressure forces on walls in sand. The numerical model was validated by comparison with model test results. In a parametric study the effects of deformation mode, aspect ratio, relative density and wall friction angle on the load-displacement behavior and in particular on the resultant 3D earth pressure force were investigated. A comparison with results from analytical methods showed that in most cases these methods are very conservative. The three-dimensional element slices theory proposed by Walz and Prager accords best with the numerically obtained results.
