主　　题：Geosynthetic Embankment Granular column Consolidation Soft soil 

摘      要：Soft clays are problematic soils as they present high compressibility and low shear *** are several methods for improving in situ conditions of soft *** on the geotechnical problem’s geometry and characteristics,the in situ conditions may require reinforcement to restrain instability and construction *** columns reinforced by geosynthetic material are widely used to reduce settlements of embankments on soft *** also accelerate the consolidation rate by reducing the drainage path’s length and increasing the foundation soil’s bearing *** this study,the performance of encased and layered granular columns in soft clay is investigated and *** numerical results show the significance of geosynthetic stiffness and the column length on the embankment ***,the results show that granular columns may play an important role in dissipating the excess pore water pressures and accelerating the consolidation settlements of embankments on soft clays.
