Abstract

Geosynthetic-Reinforced Pile-Supported Embankments (GRPSE) have emerged as an effective alternative to traditional geotechnical methods Constructing of piled embankments on soft soils. Design of pile-reinforced embankments and evaluation of plane of equal settlements is critical in the case of soft soils. If the embankment height exceeds the height of the plane of the equal settlements, settlements cannot be seen on the pavement, otherwise, differential settlements may be observed on the pavement. This problem leads to inconvenience for the users and also the failure of the embankment. In this study a numerical analysis was done to determine the plane of equal settlements of an embankment, the combination of the soil profile at the foundation is peat soil overlayered by clay and sandy soils. It is observed that the influence of the reinforcement in the embankment. The analysis was done for the 1,2,3,4 and 5 layers of reinforcement. By providing multiple layers of reinforcement i.e., 5 layers of reinforcement are used at the embankment, and it is observed that the plane of equal settlement occurred at the 4.5 m of the embankment. Variation of tensile forces was analyzed when the reinforcement is provided layer by layer.
