- Abstract
Geosynthetic reinforced and piled embankments are new type of embankments construction on soft soil foundation in recent years. Until now, the researches on this embankment structure have been carried out from theoretical analysis, numerical analysis, model tests, field tests, et al. However, in practical engineering applications, sometimes it is difficult to find a better bearing stratum. So it is necessary to study the influence of pile bearing stratum. In this paper, the influence of bearing stratum on the vertical and lateral displacement of geosynthetic reinforced and piled embankments was studied by using numerical analysis as the main method and comparing with the results of field tests, which could provide references of practical engineering applications. The results showed that the foundation of the embankments were stable as well as the deformation was small when the bearing stratum was the bedrock; there was a certain degree of penetration when the bearing stratum was sand layer; local shear failure occurred at the end of the pile when the bearing stratum was soft soil layer.
