摘要
In this paper,the three-dimensional elastic-plastic numerical analysis model of CFG pile composite foundation is created,and the variation in the composite foundation settlement,settlement of pile,cushion compression and the pile-soil stress ratio and other parameters are examined.The results show that the composite foundation settlement and cushion compression increase with the increase of the thickness of the cushion,decrease with the increase of cushion modulus.The effect of cushion thickness and modulus on settlement of pile is little.Pile-soil stress ratio decreases with the increase of the thickness of the cushion,increases with the increase of cushion modulus.
