Numerical Simulation of Dynamic Deformation Characteristics of Composite Foundation

摘要

The influence of piles design parameters such as pile diameter, pile length and pile stiffness on dynamic deformation characteristics of gravel pile composite foundation and CFG pile composite foundation was analyzed. The calculation results show that the influence of pile diameter on dynamic deformation of gravel pile composite foundation is more significant, the influence of pile length on dynamic deformation of two types of composite foundation is very small, and the dynamic deformation of composite foundation decreases with the pile stiffness increasing.
