...P. Shen; C. Xu; J. Han Three centrifuge model tests were conducted on geosynthetic-reinforced pile-supported (GRPS) embankments with side slopes to investigate the influence of pile end-bearing conditions and pile modulus on their performance. This study found that when end-bearing piles were used...

...J. L. Borges; F.

...N. Luo; R. J. Bathurst This paper presents the results of numerical simulations of one physical full-scale unreinforced embankment and two reinforced embankments taken to failure using a strip footing. The embankments were 3.4 m in height and were constructed with the same slope using the same sand...

...R. Girout; M. Blanc; L. Thorel; D. Dias Rigid piles are used to reinforce soft soil foundations and thus increase embankment stability. This technique is improved by placing one or more geosynthetic reinforcement (GR) layers inside or at the base of the embankment. A series of 33 small scale models...

...S. R. Mohapatra; K. Rajagopal A systematic series of slope stability analyses were performed on embankments supported on soft clay soils treated with ordinary granular columns (OGCs) and geosynthetic encased granular columns (EGCs). The effect of various parameters such as the undrained shear...

...C. Xu; S. Song; J. Han A geosynthetic-reinforced pile-supported (GRPS) embankment that consists of embankment fill, geosynthetic, piles, and foundation soils is a complex soil–structure system. Its key load transfer mechanisms include soil arching and tensioned membrane effects and subsoil...
