| Abstract: | A model of piled embankments within geosynthetics reinforcement is built,whose key positions are analyzed.The research shows that the setting of reinforced cushion has protective effect on pile-head plane,that the bending moments and shear forces of side piles are large,and that,the sufficient play of shaft resistance of the middle piles decreases the additional stress of the soil at the pile bottoms. |
| Keywords: | composite foundation key position numerical analysis piled embankments side pile |
