Numerical Analysis on Pile-soil Stress Ratio of CFG Pile Composite Foundation with Flexible Base

Guohua Wu

Abstract

Recently CFG pile composite foundation technology is applied in the soft soil foundation of road engineering.However,embankment is regarded as a kind of flexible base in these projects,which is different from the assumption of rigid foundation of CFG pile composite technique.Analysis was made by ABAQUS large general finite element software on the influence of pile length,pile soil modulus ratio,cushion thickness and modulus,embankment soil modulus,modulus ratio of pile-end soil and soil between piles on pile-soil stress ratio of CFG pile composite foundation with flexible base.
