To analyze the influence of foundation rigidity on the behavior of composite ground improved by rigid piles
FEM is used in this paper to study the influence of foundation rigidity on the stress ratio of pile to soil
friction resistance and the penetrating displacement of pile. And the parameter Ke which reflects the relative rigidity of foundation is proposed. Then by analyzing the development of stress ratio of pile to soil under different value Ke
the foundations are divided into three kinds----flexible foundation
half-flexible foundation and rigid foudation. Finally through a case study
