Parametric Study on Geosynthetic-Reinforced Pile-Supported Embankments
Geosynthetic-reinforced pile-supported embankments, which contain a reinforced earth platform above the piles, are relatively new earth structures developed in the recent years. The reinforced earth platform includes one or more layers of geosynthetics at the base of the embankment. The weight of the embankment and the surcharge above are largely transferred onto the piles so that the soft soil between piles carry less load and the total and differential settlements of the embankment are reduced. A numerical study was conducted to investigate the deformation behavior of geosynethic-reinforced embankments on deep-mixed columns by considering five major influence factors: the elastic modulus of deep-mixed columns, clear spacing between columns, elastic modulus of soft soil, and tensile stiffness and layer of geosynthetics. Numerical results suggested that the inclusion of geosynthetics in the earth platform can enhance the stress transfer from soil to columns and reduce the maximum and differential settlements on the crest of the embankment, and the maximum and differential settlements on the crest of the embankment decrease with the number of geosynthetic layer and the elastic modulus of soft soil and pile material.
