Serviceability design for geosynthetic reinforced column supported embankments
TL;DR: In this paper, the authors highlight the need for coupled arching stress-deformation models to describe accurately serviceability behavior and raise questions about the longterm performance and the manner in which acceptable performance has been achieved in the short-term in several field case studies.

Classification and characteristics of soil arching structures in pile-supported embankments
TL;DR: In this article, a series of Discrete Element Method simulations were performed to investigate the evolution of soil arching structures under different conditions with emphasis on the embankment deformation behavior.

“Soil arching” for piled embankments: insights from stress redistribution behaviour of DEM modelling
TL;DR: In this article, a total of 131 2D trapdoor-like discrete element method models were conducted to present the soil arching effect, stress state and deformation behaviors of the piled embankments.

Cambridge Geotechnical Centrifuge Operations
TL;DR: In this paper, the authors show that the stress/strain behavior of soil alters with change of effective pressure p and specific volume v. The range of values of a new equivalent liquidity LI5 = LI+0·5 log (p′/5) associated with yielding is 1·9

An analytical model for arching in piled embankments
TL;DR: In this article, a limit-state equilibrium model with concentric arches is proposed for the design of piled embankments or load transfer platforms with geosynthetic reinforcement.

An experimental investigation of soil arching within basal reinforced and unreinforced piled embankments
TL;DR: In this paper, the authors evaluate the effects of pile-subsoil relative displacement, embankment height, cap beam width and clear spacing, and geosynthetics with different tensile strengths on stress concentration ratios and settlements in the embankments.

Model experiments on piled embankments. Part I
TL;DR: A series of twelve 3D laboratory model tests was performed on piled embankments as mentioned in this paper, where the vertical load parts on the piles, on the geosynthetic reinforcement (GR), and on the subsoil could be measured separately.
