Additional Stress Distribution in DJM Pile Composite Foundation and Simplified Calculation Method

Abstract:

Although DJM-Pile have a good effect on strengthening soft foundation,theories about additional stress are too complex or too simply to be used in project well.By adopting FEM software with considering of friction between soil and pile,simulate the additional stress in composite foundation because of DJM pile construction and compare with results gotten in Bossinesq method.The comparison shows that the distribution of additional stress is very similar.So considering several major influential factors,the paper updates the Bossinesq method and brings forward a simplified calculation method.
