Analysis of Deformation Rule of Cement-soil Pile Composite Foundation Under Embankment Load

摘要

Based on finite element numerical calculation method,the paper systematically analyzes the effect of the fill height,the fill modulus,the length of pile and the pile modulus on the deformation of cement-soil pile composite foundation.It shows that the fill height and the pile length have greater influence on the surface settlement and the ground lateral displacement,which are the major influential factors of composite foundation deformation;the fill modulus and the pile modulus have little influence,which are the minor factors influenced on the deformation of foundation.
