Based on the improved three-dimensional finite element model, this paper studies load transfer mechanism of pile-supported reinforced embankments. The model uses an elastic medium to replace soft soil subgrade, which reduces calculation depth subgrade and improves efficiency model. validity is proven by field test results theoretical results. By changing cohesion, internal friction angle, modul...

In this paper, the use of geotechnical centrifuge and numerical modeling techniques to investigate influence geogrid reinforcement EPS interlayer on lateral earth pressure backfill surface settlements behind gravity abutment pile-supported is reported. According principle equal strain, back structure, foundation, material, grid material were simulated, centrifugal model test for two types abutm...

The shear strength of geogrid-reinforced ballast is often dependent on the aperture size geogrids and nominal ballast. This paper presents a theoretical analysis based probabilistic mechanics how affects interaction between particles geogrid. Unlike past literature, in this study, properties particle distribution analysed using Weibull distribution. probability grain interlock proposed to descr...

This study used finite element analysis to investigate the influence of using two reinforcing systems, geogrid and grid anchor, on bearing capacity a circular footing resting sand. The parameters studied were effect number reinforcement layers (N), depth ratio topmost layer (u/d), vertical spacing between consecutive (h/d), length (L). results showed that layout had very significant behavior re...

This paper presents two-dimensional (2D) and three-dimensional (3D) numerical simulations of a half-scale geosynthetic reinforced soil (GRS) bridge abutment during construction load application. The backfill was characterized using nonlinear elastoplastic model that incorporates hyperbolic stress–strain relationship the Mohr–Coulomb failure criterion. Geogrid reinforcements were linearly elasti...

The method of encasing the stone column with a proper type geosynthetic material is widely used technique to provide required lateral confinement and avoid dispersion granular into soft clay. Along improved ultimate load capacity reduced settlement bulging, encasement preserves easy drainage ability columns. This paper presents finite element analysis results hypothetical embankment on soil dep...
