Settlement calculation of CFG pile composite foundation based on load transfer method

Ling Zhang

Abstract

With thoroughly analyzing the load transfer mechanism of CFG pile composite foundation,considering the characteristics of the interaction among pile,soil and bedding course,according to the assumption and the simplified distribution mode about the vertical displacement of pile-soil element,an elastoplastic load transfer model is introduced;and considering both upward and downward penetration displacements of piles,an basic differential equation of settlement calculation of CFG pile composite foundation is established based on load transfer method.Then,a new method for calculating the settlement of CFG pile composite foundation is developed.This new method is applied to analyzing an experiment;and the results show that the calculated results are consistent with the real values.This method can decrease the cost of calculation and can be conveniently applied to the practical engineering.
