Pile And Soil Interaction Analysis. Piled Raft Foundation

This paper present a new 3-dimensional non-linear model for analysing the interaction of raft-pile-soil system. Different distance between piles is introduced respectively to compare and analysis coordinately different failure mechanism and bearing capacity characteristics of composite foundation. In view to the mechanical character of the contact surface between pail and soil seem to rather complicated and it tend to appear stress concentration in the soil mass around the tip of the pile, which enhance further study on the interaction theory.Designers used to design foundation without considering the stress-strain relation of the soil mass.. In this thesis, deformation of every element by finite element method associated with the consideration of the soil抯 elastic-plasticity non-linear condtitutive relation.
