| Abstract: | Mindlin formula in elastic medium and the layered summation for shallow foundation are adopted in this paper to analyse the variaton of stress ratio of pile-soil. replacement ratio, dosage and pile length. It is proved that we can well design the flexible pile composite ground by controlling the target stress ratio of pile-soil. |
