| Abstract: | The soil is treated as a layered two-phase mixture and the interactive influence of fluid flow and solid deformation is considered. The influence functions of dynamic interaction between saturated soils and structure with disk and barrel loading are obtained. Theoretical procedure of the dynamic interaction with pile and layered fluid-saturated soils is developed by an indirect boundary element method. Finally, dynamic impedance of piles in layered fluid-saturated soils is performed which can prove the present method true. The effects of fluid flow of two-phase saturated soils on dynamic response of piles are investigated. |
