摘要
本文通过对碎石桩复合地基的简化．采用有限元方法分析了复合地基的附加应力与桩身应力的分布特征；讨论了桩土应力比与桩土模量比，以及荷载及置换率的相互关系；揭示了桩体变形和复合地基塑性区扩展的基本规律。即从不同角度探讨了复合地基的承力性状。
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.
