“…Chen et al (2008a), Abusharar et al (2009) and Deb and Mohapatras (2013) showed that the efficiency of the piled embankment improves greatly when GR is used. They found that the load on the piles was much larger with, respectively, a 2D analytical model, an axial-symmetric analytical model and in 2D experiments.…”

“…However, it has already been argued in Chapter A. Abusharar et al (2009) and Le Hello (2007) use a 2D geometry, whereas Love and Milligan (2003), Stewart (2005) and Russell and Pierpoint (1997) use a 3D geometry, Chen et al (2008a).use an alternative 2D approach. c as recognized by Cornet and Horgan, 2010, In practice, the geometry of many piled embankments falls within the 'partial arching' area.…”

Piled embankments have been widely used in road engineering. A unique mechanical behavior which is called soil arching effect in piled embankments is a key factor in load distribution. In this study, a modified 3D finite element model is presented to analyze the soil arching effect in piled embankments. The interaction among the pile, subsoil and embankment fill is simulated by springs with various stiffness values. A field test is conducted to get the actual engineering data. Based on the results comparison, several contrast numerical analyses are performed by changing the pile spacing. The critical maximum and minimum heights of the soil arch can be clearly obtained via the numerical model and the critical height of soil arching of the numerical model is consistent with that of Hewlett's theory. The numerical model is not only easily implemented but time-saving, which is a new method for researchers to analyze soil arching effect in piled embankments.

“…Pile/column supported embankments improve structural stability and reduce embankment deformations [2][3][4][5][6][7][8]. The inclusion of geosynthetic reinforcement just above the pile caps enhances the load transfer efficiency, minimizes yielding of the soil, and reduces total and differential settlements, Han and Gabr [1]; Russell and Pierpoint [9]; Varuso et al [10]; Rowe and Li, [11]; Bergado and Teerawattanasuk [12]; Briançon and Villard [13]; Li and Rowe [14]; Rowe and Taechakumthorn [15]; Abusharar et al [16].…”

The numerical modelling of geosynthetic-reinforced piled embankments using both the finite element method (FEM) and finite difference method (FDM) are compared. Plaxis 2D (FEM) was utilized to replicate FLAC (FDM) analysis originally presented by Han and Gabr on a unit cell axisymmetric model within a geosynthetic reinforced piled embankment (GRPE). The FEM and FED techniques were found to be in reasonable agreement, in both characteristic trend and absolute value. FEM consistently replicated the FDM outputs for deformational, loading, and load transfer mechanism (soil arching) response within the reinforced piled embankment structure with a reasonable degree of accuracy. However the FDM approach was found to give a slightly higher reinforcement tension and stress concentration but lower reinforcement strain at the pile cap than FEM, which was attributed to the greater discretize of the model geometry in the FDM than in FEM.
