Abstract: 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, applicability of the presented method is proved.

Key words: foundation rigidity, composite ground improved by rigid piles, behavior
