This present paper deals with the interaction analysis method of pile foundation established on thick and soft groundsill. A contact interaction model is given to simulate the interaction between pile and soil
soil and base slab. As for the superstructure
it uses substructural method to take its stiffness into account to the settlement of foundation. It regards the soil as elasto-plasticity
and uses infinite element to account for the effect of far field groundsill. In the end
an analysis example is given. From the results
It can bee seen that the analysis method adopted in this paper works very well.
