| Abstract: | Based on the simplification model of stone pile composite ground the distribution characteristics of additional stress in ground and stress in piles are analysed with FEM in this paper.The relationship of a the pile-soil stress ratio with pile-soil modulus ratio, with the load and the substitution ratio are discussedl and the basic rules of pile deformation and plastic zone spreading in composite ground are described.The bearing capacity behavoir of foundation is studied from different angles. |
